Can anyone confirm whether or not I can run a 20x9 +35 front and rear and offset the tires with a 235/35 front and 275/30 rear on my RWD f sport?

235/35 and 265/30 have the same rolling diameter front and back. 275/30 is bit taller than 235/35 and will not match the front axle rotations. Having said that the transmission might not be happy by compensating the difference in the long run.

so you’d recommend going 235/35 and 265/30?

I'd wait for more responses from other members and see what they say. In the meantime check out what Scotty says about mixing tires and the effects of it on longevity of transmissions.

Hmm according to this tool 235/35 and 275/30 has the same outside diameter...

235/35R20 and 275/30R20 are the same,

265/30 is 6mn smaller than 235/35, granted it's assumed safe to stay within 9mm of factory set up. So shouldn't be a problem either way.

You can run the 235/35 and 275/30 as far as wheel diameter goes. Regardless, since it is RWD, even if there is a difference it diameter, it shouldn't cause any issues since its only driving the rear wheels. As for the fitment, I'm not sure. Might need to do your own research and see what setups others are running.

I run 245/35s on 20x9 squared, I don't see the reason to run staggered tires on non-staggered wheels and eliminate the chance of being about to rotate front to back. if you wanted to run 275s in the rear, why not get 20x10s back there so your sidewall height would look "normal"
