Tire Size Help for 20s on F32

Know this gets asked a lot but seems like my setup will be a little different than most so wanted to get some input.

Looking for best tire size for the following wheel size. its my understanding that this particular size is rather conservative for what can be typically fit on the F32. I will be putting spacers on the front to make it more flush. proly 10mm as when I test fitted the wheels I had plenty of room to work with.

Wheels:

20x8.5 et45
20x10 et50

I will be lowered on BC Coils rather low and am looking for a flush look.

Appreciate this!

Is there anyway to fit a higher profile tire on this setup? never been a fan of the extremely thin tire look but I assume its necessary on the 20s.

OEM diameter is 26". 245/35/20(26.8") & 285/30/20(26.7") being taller and girthier might contact the strut, spring perch, or fenderwell liner while turning at full lock. try it and let us know.

as wheel diameter increases, aspect needs to be reduced to maintain the same diameter for a given tire width. if you wanted more sidewall 19's or even 18's would have been a better choice

Its not pertinent. I already have the wheels, as they were a hell of a deal, so I am moving forward with it.

Thanks again. Any particular tires that are popular around here for this setup?

Thanks.

Really like the Hankooks but looks like the smallest width they have for the front would be 245/35/20. Is that pushing it or look goofy etc?

245/35/20 are just fine for the wheels and should work well. More comfort, more protection to the rims. On OEM chassis, there can be a slight rubbing of fender liner at full-lock or near that (depends on the car and tire model). However, this tire size is the biggest diameter you can fit in, and not sure, how it would work when lowered... Worth research.

A great list of tires suggested by alohasurftoad. I would add there only Goodyear - Eagle F1 Asy5 as the choice of comfort, and Eagle F1 Supersports as a sharp handling option.

btw, why do you prefer V12 evo2 over S1 evo3?

Thanks for this as well. SO 245 in the front works for the wheels and suspension but uncertain about when lowering heavily? Which I will be doing.

I do see a decent amount of 245s in the front on the "slammed" thread but no telling what they had to do to not get it to rub.
