wheel sizing question

onewheelneil · #1 (**permalink**) 10-12-2009, 08:17 PM

I bought my truck with the wheel and tire combo(pic below) allready on there.All I know is that they are 17x8 helo's with 37x12.50 parnelli jones and my lift is a 6inch superlift.My problem is they rub on the springs pretty bad,way before full lock.I'm gonna stay with 17's because the tires are new and they perform well offroad but what offset and back spacing is going to be enough so they don't rub? I allready picked the wheels out

just want to get the spacing right the first time because we all know returning wheels is a major PITA!!! Thanks for any help.Oh,by the way I considered spacers but I don't trust even the super strong ones to hold up in the conditions I put my rig in!!! Not an option.

as long as those wheels are a 4.5 bs youll be okay.

10/4. How do I figure out what the back spacing is on the ones that are on the truck as of now?

I apologize for being an idiot!!

im trying to find the spec chart for those. i ran the same wheel in a 17" and had no problems rubbing. however every truck is different. im sure they only made it in the 4.5. worse case it may be a 5 inch and you still shouldnt rub with that

I wonder why these damn things are rubbing??? The tires are clearly hitting on the springs.If I go with a 17x9 with a 4.5 wouldnt they rub aswell?

measure the back of the rim to the outside edge. thats your backspacing.
