I have not found any info on going one size up on the width. I know a 205/45 is at the max for what should be installed on a 6.5" wide wheel. Pictures would be great as well. I plan on installing 10mm spacers on the front and 15mm spacers on the rear as well as 205/45-16's in spring. I like the 16" Abarth wheels too much to change them. Info/feedback welcome.

The bigger thing is that they're TALLER than stock, reducing acceleration and raising the car. However, it's about halfway between the stock 16 and 17 inch diameters so it's not so bad as the extra height on 17s. The wheel width issue isn't as big a deal as long as there's no clearance issues.

The difference is under 2% from the 195's. I like smaller wheels and meaty tires. There is crap for selection in 195's anywho. I thought I saw that redred was running 205's. Sent him a PM but no response as of yet. I'd like to see how they look beforehand.

The speedo will be closer to accurate versus the stupid stock 195/45-16 size. Not as accurate as the 205/40-17 size though.

Size difference is negligible at best. I love my BFG Sport Comp 2's! (saw your PM, haven't had a chance to respond yet!) I have over 10k miles on them already and tread is down to 5/32. I've had them on a track on a super hot day (112 degrees F) and they held up amazingly well. Multiple canyon runs, and generally very aggressive daily driving.

I don't have photos, but I'll see if I can find a little time later today to snap a few for you. I will tell you this, get your car lowered and aligned at the same time. You will need a little additional negative camber up front and most likely some shims in the rears. To get the camber I wanted up front, I had some SPC Camber Bolts installed. I would highly recommend you get the car lowered and aligned if you plan on getting them.

Hrrrrmmmmm, I have no intention of lowering the A but I had every intention of spacers (10mm f/ 15mm r) with the stock A 16's

Fair enough. I can't speak to whether or not they will work with spacers since I don't have them on the car. I can send you pics, but it won't really be an accurate representation of the direction that you wish to go in.

Not at all. In fact I am sure it will be fine with spacers at stock height. I just can't vouch for it since I don't have that setup.

What? The speedo wasn't calibrated for the 16s, just the 17s?? I ass-u-me-d there was a different calibration for each wheel size.

I run the Federal 595 EVOs at 205/45-16 lowered with Nuespeed springs. I've experienced no rubbing, even with aggressive driving (track/canyon/autocross). I like how they filled out the wheel well better. I opted for the 16" wheel at the dealer because I assumed (incorrectly) that I'd come across factory size tires easier and cheaper, as I tend to wear them quickly. I'll likely go to a 17" next spring, unless someone wants to trade me now?! :)

No spacers, though I've considered them. Opted against for now, as I'll likely just go with a new wheel for next autocross season.

Just did the Zonker mod to the rear springs this evening to level the rear end. A set of 4 15mm spacers on in the mail. After they are installed I will see how it looks/handles. I do enjoy the look of meaty tires. Maybe a set of 16x8 Stance Mindset wheels in black and 205/45's will finish it off. Baby steps as I really like the 16" A500 wheels since they match the paint.

I have KW V1's with 205/14/16 Toyo R1R's and I don't rub unless I am pushing the car hard at the track. It only rubs a little on the inner fender well when turning.

Hi guys

I am new to this forum. I am thinking to put 205/45/r16 Toyo R1R on my 16" rims so i am trying to find absolutely as much information as i can. And i ended up here.

I read that some of you have the rubbing trouble with them on and some of you dont.
I have ordered the Eibach Pro Kit springs and will put them shortly on my car. Will there be a problem with rubbing if i put the 205/45/r16 on?

Many thanks,

Shant

I don't think you'll be rubbing with 205/45-16s - the rubbing has been reported with 215/40-17s, usually with a lowered car. While the stock 16" wheel is a bit narrow, I think you'll be fine. Diameter is halfway between the OEM 16 and 17 sizes so you won't be raising the car much or losing much in the way of acceleration compared to the stock diameter. Let us know how it goes if you autocross/track - sometimes I wonder if this wouldn't be a good way to go for best racing on a stock (or nearly so) car...

Tires still slip but not as much as before with the stock tires... Those things were ice skates

This is the worst decision to take of my life lol. I feel a bit more relaxed now that i got a few replies so i will have to think extra carefully and take my decision. I am going on a track day on April 5 so i need to get my car ready by then.
I will let you guys know how it is if i eventually put 205/45.

Thanks,

I rarely put people at the back :)
I also nearly never put heavy things at the back :P

I will most probably put the semi slicks on as its something that i want a lot for the track day, and i also read online that they are okay in wet conditions as long as you drive normally.
I am from Cyprus so we rarely get bad weather here.

I have gone from 17" back to the stock 16" as part of my efforts to lower the car for racing. I lowered 11/4" X 4. I am using Toyo R1 that I also keep on for DD 205's My lap times dropped dramatically with my small tweaks. I also went to the 28mm torsion bar and a track/street alignment done by the track technician. BTW he told me that for racing he recommend (strongly) that no spacers be used as he found that on the front suspension, spacers affected the front end geometry. Ciao

There are more tires options in that size and should also correct the speedo issue. That's the size I plan to go with when the OEM tires run out. Hopefully the madness ecu helps with that:-)

SORRY I just realized that these pics don't show any shots of the tires fron front or back. Anyway the 205/45 Toyo's have been fantastic on the track. For the Texas Mile 1 mile straight sprint I will put the 17's back on with their harder compound bridgestones

With my 16" winters and 195/45-16, my GPS is always 3-4 MPH slower than speedometer.... lesson learned; my next set of 16" winters will be 195/50 or maybe 55.

Guys another thing that i would like to share with you.

Yesterday i found out that in order to put 205 on the 16's you need to go for 205/40 instead of 205/45. Because once you go wider thoe tyre goes taller too. Thats what i was told. And looking at a few pictures i think he was right.

I dont want to do things i am not sure on my car unless if i have extra money to throw so i will most probably wait and put normal tyres for the moment.

Things are very confusing so i dont want to risk anything.

205 is section width in mm. section width is the widest part of the tire measured with a rim that's about an inch narrower than the advertised section width (this may vary a little, i'm not sure of the actual rule) . 40 is the aspect ratio. that's the ratio of the sidewall height to the section width in %. generally for a 5% change in aspect ratio you would change the width by 20mm. if the difference in width is 10mm you can chose whether to change aspect ratio or not. tires may also have a diameter advertised or a revs per mile that you can match up if you are not sure. there are online tire calculators but the actual tire may vary from the calculator by a small amount depending on brand and application.

also the tread width on a particular section width can vary by up to an inch!!.. my next tires will probably be from continental because they have tread that's damn near the section width but my current tires are about 3/4 inches narrower at the tread as compared to the continental tires i was looking at. so if you are going for an agressive look with lots of tread you may want to use a large site like tire rack to make comparisons between tread width.

Since this car also comes with 205/40-17s which are almost an inch taller than the 195/45-16s, the 205/45-16 isn't a problem from a clearance perspective. In fact, they are pretty much in the middle between the two sizes. I'd agree that the 40 series would be preferable from a performance perspective due to the shorter diameter and sidewalls but you have to be able to find the size in the tires that you actually want to use. The Toyos, f'instance, don't come in the 40 series.

It's just a formula to calculate tire diameter.

205/45-16
*205 = section width in millimeters, not to be confused with tread width
*45 = sidewall height as a percentage of section width
*16 = wheel seating bead diameter in inches, not to be confused with overall wheel diameter. FYI most 16" wheels have an overall diameter of approximately 17.5"

So, 205*(.45*2, you have two sidewalls)/25.4 + 16 = 23.3"

This diameter is still 0.2" shorter than the 205/40-17 stock tire size that's been shown to provide accurate GPS speed readings, however it's 0.4" taller than the stock 195/45-16 tire size is.

So, 205/45-16 will be closer to having an accurate speedo than the stock 16's, but not as accurate as the stock 17's. This is frankly a rare instance where the OEM put rather drastically different tire diameters from the factory. Going with a taller 16" size like 205/50-16 ends up being too tall and will both risk rubbing the wheel liner and show a speed slower than actual, which is generally a bad idea. 215/45-16 is only 0.1" taller than the 205/40-17 diameter and probably a reasonable suggestion, but the added width again adds risk for tire rubbing.

Long story short, 205/45-16 is the correct tire size for 16" wheels on the Abarth, the factory screwed up with 195/45-16.

what, an aerosol can and a lighter, how dangerous can that be??? lol! i do this with quad tires... usually outside and i stand back and use the can as a flame thrower to light off the aerosol inside the tire just in case... don't want to stand too close to that thing if you use the wrong amount of aerosol. not that i've ever had a real explosion but it's just freaking standing with a lighter an inch from something that is about to expand quite aggressively.

I'm super excited, I got my 205/45R16 Firestone Firehawk Indy 500 in today! These tires are called called Bridgestone Potenza RE003 in the rest of the world. These are, to me, the spiritual successor for the RE011 as the RE71r is just a cheater tire to pwn at autoX. Anyways, I disgress.

These are just a hair taller than stock:

I picked up General GMAX AS-05's in 205/45/R16 last spring and run them on the stock abarth 16's. Much more comfortable than the oem 195's but you do lose a little bit of sharpness in steering. I think they'd be a better fit on 16x7 wheels. The also seem to have gotten very noisy after 11k miles.
