I picked up some 19x8.5 wheels and originally intended on doing 245/35/19's all around, however after doing some research 255's are for whatever reason quite a bit less expensive, and listed as max with for an 8.5" wheel. Anyone foresee any issues running this?

I think it may be a little bit too much width on the front. It should be no issue on the back as the current Ti Q4 staggered configuration has 255/35x19 on the back (with 9" wheels not 8.5"). The front on the QVs is 245/35x19 on 8.5" wheels. I would suggest to stick with any of the proven OEM configurations and 255/35x19 on 8.5" wheels isn't one of them.

@Racer Z has 255 35r19s mounted on 19x9 wheels. Ask him regarding his experience.

255 width tires could in theory fit on 8.5" wheels but I wouldn't recommend it. Ideally 9" or 9.5" wheels would be better.

Stock size on the B8 Audi S4 was 255/35/19 on 8.5 width rims. Kind of normal fitment.

We have installed several sets of 255/35-19 tires on 19 x 8.5 wheels and they fit really nicely and the car definitely feels better with a little more rubber. The 255s don't look stretched on the 8.5 wheel at all.

After driving with these installed I really scratch my head why they weren't a stock size.

Fuel economy is my guess.

Hopefully someone can advise. I recently purchased a Ti Sport Giulia with the 5 hole wheels. According to the window sticker it has 19"X8" and 19"X9" aluminum wheels. The front tires are 225/40/R19 (89W) Pirelli P Zero run flats. The rears are 255/35/R19 (92W) Pirelli P Zero run flats. The door jamb tire sticker says that these are the correct sizes for the vehicle. It is my understanding that these are Summer tires and before the Chicago Winters come I will need to replace them with an all season tire. My question is should I stay with those same tire dimensions and what would be a good recommendation for an all season tire, with or without run flats. I do not know how to tell if a tire will fit on a 8", 8.5", or 9" wide wheel. I appreciate any guidance.

Sweet this looks just right! what tires are on there? I'm looking at the Firestone Firehawks, normally I'd go Michelin PSS but lacking in the funds dept. and they have really good reviews.

Actually got these mounted a while back. 255/35/19 Firestone Firehawks on 19x8.5 (ebay seller...ehhhhh)

@JeFizz - I have the same setup as above

So, at 19x8.5, which 5-hole wheels are these? I'm considering the same, but I (think) I only have 19x8 wheels (OEM 5 hole).

I don't remember what was said in the other topic, but I thought you say you had 8" wide with 255's.

 

[blisstik]

@JeFizz my bad that’s 8.5 width. Mine are just 8s. It could use some spacers but I’ve never trusted them.

Ideally you'd want a 9" wide wheel to run 255/35's. 255 will work but look bulgy. It's always best to look at the tire manufacturer's recommended wheel widths for each respective tire. I have some 18x9 +34 with 255's sqaure and I love it.

Nice TE37s

I actually like the bulge. Reduces some of the wheel gap and I am not looking to lower the car.

Hi. Great look!! So 255 w et34 look perfect. What spring are you using?

I run 255's all around, no issues at all.

Just got some Federal Evoluzion ST-1 255/35/19's mounted onto new 19x8.5" wheels - rides really nicely and no issues with fender rub or bottoming.

Looks amazing. Are these on factory spec wheels?
