Max Tire/ Rear 20" Wheel. 305?

ts1412 · 03-30-2017, 02:56 PM

Hello all. I have a quick question to all my lowered friends (Swifts).

I have a 20" rim, 11" Diameter, and +20 offset (rear) and I am wanting a wider tire. Can I go 305 without rubbing? 295 is the safe bet, but I like the flush look and dont care for spacers.

Any suggestions and photos would be much appreciated!
EDIT: I tried the search bar but couldn't get a straight answer for my question.

i am running 20x12 +20 with a 315/25/20, its a minor stretch, and zero rubbing a -2 camber. I can actually put a finger between the tire and fender despite being low (top of tire to fender arch in height)

a 305 width is easy on your wheel specs

here's the problem:
a 305/30 is taller than stock at 27.2
a 305/25 is super short, at 26 inches.
OEm is 26.9

What size tire are you running in front? I believe you need to be within 3% of the rear height not to **** up your speedo

305 no problem at all

Thanks all. Right now my fronts are offset at 9" wide +25 and are just right. The rears I currently have 285/30/20, and as you can tell, look way too small!
