what the max widest for a 18incj 8.5 j wheel

whats the widest tyre you can use on a 18ich 8.5 j wheel

Featured Replies

255 is the most common, you can just get away with 265 but you will have a small amount of sidewall pinch.

 

 

I tend to use this site for tyres as a rough guide: http://www.tiresandco.ca/equivalency-tables-advice.html

would a 275 be safe so would I use a 275 35 18 or 275 30 18

I would not use 275 on a 8.5j wheel.

 

I'm sure people on here are, and that they are fine with it. But the amount of tyre pinch would be horrendous, and the car will handle like a dog.

235 - 245 is a typical 8.5" width, 255 would be ok and the maximum you would want to use.

 

I doubt anyone here is using 275 on one, remember 8.5" is a typical aftermarket FRONT wheel width on the Z.

 

Most people are running 9.5" rears with a 265 - 275.

mt front wheels is 8j and rear is 8.5j

will I get away with a 265

i got 9 on the front with 235 40 18 then on 10 inch on the back with 275 35 18 but i dont think yourll get away with 275 35 18 on a 8.5 maybe 265

yes 275 would be pushing your luck am going to try a 265

245 IMO. It gives you a completely flat tyre wall on an 8.5, any wider and the tyre will roll round on the rim too much and will look a little donut-ish!

 

My fronts are 8.5" wide with a 245, I'd not go any wider. Narrower and you start getting stretch...yuk!
