I have a 2023 F Type R. The tire sizes on the vehicle are 255/35R20 on the front and 295/30R20 on the rear. I’m going to change tires and I was wondering if anyone has increased the tire sizes to 265/35R20 on the front and 305/30R20 on the rear? If so, have you experienced any negative issues with the increase tire size.

I researched a lot of tires and believe it or not, I put the Firestone Firehawk Indy 500 on my F-Type R and they are great tires. They really stick well and I feel they are better than the stock Pirelli tires and cost a lot less.

Thanks for the recommendation. Did you increase the tire size?

Those tires seem to take the entire rim... not sure without offset and new wheels you could do. I love the stock size. were you looking for more width or a little height?

It's not so much the tire size but the availability of the tires. I was looking at Continental Extreme Contact DWS 06 Plus. The front tires are not currently available in 255/35R20 but the 265/35R20 are.

Watch the diameter of the tires if you go wider. Different diameter on the rears will change your indicated speed and odometer (assuming they are tied into the rear tires). Online tire firms have a calculator you can use.

I installed Michelin PSS, because they are far superior on the track to anything else I have used. And there are zero issues going up to the larger tire.
