Can a 255/35/19 tire fit safely on a 19x8.5 rim?

 

yes, but kinda bulky looking.

 

you'd be pushing the envelope. i've got 245/35 on my 19x8.5. looks great, fit is about 5mm more than i want. it's just enough where the rim is 'protected', but it's not bubbling out. imo, i would get at least a 9" rim for that tire width. i know they are not a common size, i'm just saying that a 255 on 8.5" is pushing it... really far.
hope this helps.

 

but the stockers are 245 on 18x8 tho...so i don't see how 255 would be too large for 8.5

 

if the tire is stretched you get curb rash?? correct?

 

When you hit the curb with the face of your rim you get "THE RASH"

Having a tire that is slightly wider than the rim (assuming proper inflation) will help prevent "THE RASH" if you slide up along side a curb.

 

regardless of tire stretching or not, curb rash is possible. even if your tires are past the lip of your rims. the force of the car even at a roll, will cause the tire to get squished and then tickle your shoes.

 

245's on my 8.5" front rims looks a little stretched IMO. I am going 255 when I order new tires. I also ran 255's on the rear of the stock 8" wheels with no problem. The tire did bulge a bit on a 8" rim. I wouldn't recommend it, but people are even running 275's on the stock 8" wheels without any reported problems.

 

Whoa 275 on a 8" rim is foolish espeically with hard driving in corners. Makes no sense.

Well it seems like 255 on a 8.5 should be ok from what I can tell.

 

I've had 255/45 r17 michelin pilot sports on the stock 17in rear rims for over a year now. No problems ever.
