20x11 et32 fit 305/30-20 in F80 rear?

Looking to fit 305/30-20's on 20x11 et32 on an f80, will they fit? 295/30 will but I was wondering if anyone has stuffed these in the fender on a 20x11 with 32 offset.

Can someone point me to a calculator?

Is as close as it gets. 44 is far from 32.

I will be buying Apex for my track set but this is for my street set and I have a real good deal on some 305's.

11et37 with 305 and -1.9 deg rear camber rubs the outer fender. 11et32 with 305 will need a lot of rear negative camber to avoid rubbing. 11et32 has a 0.47” more aggressive front spacing than 11et44 and has a 0.20” more aggressive frontspacing than 11et37. I personally would not run a street setup more aggressive than 11et37. I’m running HRE R101LW with a 19x11et42 305/30 setup. I think it’s perfect.

Edit: I missed the 305/30-20 because I was thinking 19” (my setup). For 20”, you need 305/25-20. 305/30-20 is guaranteed to run badly at 11et37.

Thanks. I have a 32 offset so it would be worse. I believe I should be happy with 295/30-20 with this 32 offset??

295 should also be 295/25-20 but a 295/30 on a higher offset might clear. The slightly stretched sidewall will help a little. You might also need rear camber of -2.5 or higher to help with clearance. Is the 32 offset fixed on this set of wheels?

😂 I always tell my wife wheels are just like shoes for her. You need different styled wheels for looks on the street and then lighter & wider performance wheels for the track. However, all I know is my wife gets shoes or purses or jewelry when I buy wheels and other parts for OUR cars. The “OUR” never works.

It should be fine as long as it’s not an extreme performance category tire which tends to run measurably wider than a max performance category tire. You’ll probably need to run a little bit more negative camber with extreme performance category tires to prevent/limit contact.

I saw your pic in another post and saw your 20's in your sig. do you think my offset of 32 is going to make a difference to rub? Simple math should say 305 will rub.
