1 RARE T

2020 S3 with rotor wheels. Stock size is 235/35/19.

I have a brand new set of 255/35/19 Yokohama summer tires. Got them with a different car and swapped some all-seasons on it. Traded the car.

Bone stock everything. Can I install the 255's with no issue?

I realize the whole only an 8 in rim thing but I have a company truck so this thing only gets out of the garage on a limited basis and driven like an old lady.

Will they rub or cause other problems? Anyone doing it?

Ok, somewhere to go for clarification?

I used this website to figure out clearances when I bought my winter tire setup a few years ago. I found it to be quite helpful and think it might be for you as well. You can also search my post history as I commented on a few threads on tire and wheel sizes.

Thanks a bunch for the reply. That site is super informative.

If I'm understanding the info after putting in the sizes and vehicle, the 255's shouldn't be a problem.

They're very close in size.

If someone wants to verify, I'm all ears.

Thanks again, FlorS3.

If you measured the clearances to the suspension and body components on the existing tires and the calcs for the 255s don't show a problem I would think you are good to go. The 255s are only 10mm wider to the inside and outside. I have the 235/35 R19 tire setup on my S3 and there is a fair amount of clearance (much more than 10mm) to suspension and body parts.

The 255s will have a higher sidewall (35% of 255 vs 35% of 235) so your revolutions per mile will change (fewer?). What did the calculator predict for speedo error?

Hey,

60mp/h on the speedo will actually be 61.3 so no big change.

For anyone interested, finally got the tires installed.

Zero issues and actually looks killer.

More muscular. Ride is improved with more sidewall.

I dig it.
