Tyre size for 20

[inzaghi316]

I have a 2012 Expy El ltd.
It has 20" stock rim.
Current tyre 265 55 20.

Could i change it to 275 65 20 without any other modifications. If not then 275 60 20 will be good as i need some height.

Thanks

265/55r20 = 31.48"

275/65r20 = 34.07" ... would almost certainly need a 4 corner lift kit

275/60r20 = 32.99"... 33's fit stock I think? +0.75" of wheel in all directions (or more like +1" if your tires are worn out), +0.75 - 1" height


PS if your shocks and springs are good. If they're shot, you're screwed.

So 275 60 20 fits without any issues?

Eh.... very highly likely?

IDK ask around, I've always been slightly lifted

Or just look yourself, if your tires are older measure +1" in every direction up down left and right, then repeat at wheels turned to the right and left... and see if any potential rubbing problems are present

275 treadwidth should be a non-issue since people run much wider, so probably safe to disregard that part

Will do. Maybe i think 275 60 20 will fit without issues. Will chk on other forums too.

Dont forget you will need to recalibrate your speedo or it is going to be giving the wrong speed reading and our boys in blue can make that an expensive issue very quickly!!

Nah

31.5 >> 33 is +4.8%

+2 mph @ 40, +3 mph @ 60, + 4 mph @ 90

Just go 2-3 mi "slower", keep the needle below 80 (and never pass 85) and you're good.


Plus your odometer will read a hair lower lol
