Tire Sizes

[jeeprunner4444]

Hey Guys,

I need help with my 2009 Jeep wrangler Jk unlimited 4door. I have 17 inch stock wheels but am replacing them with Helo HE878 wheels. The specs are 17x9 and offset 12. I am also putting in spacers. I need to know how wide can I go with new tires. I am looking to go wider not bigger but want to make sure the tires wont't rub on the flares. Tires I want are Goodyear Duratec. Please help!!!!!!!!!!!!

Looking to keep size at 17 but the width is what I need to know. Also, the spacers are 1.5

thanks

Last year I put on 17 x 9 with 285 70 R17. I had to add a terraflex leveling kit to keep them from rubbing, though only at extreme turns. The backspacing on those are listed at 4.75, I'm not sure what that is in mm.

Be aware, that your tires are going to stick out quite a ways from the fender.

Anyway, here is the website I use when messing with tire sizes.
