Hey guys

I picked my self up a set of 97 ZQ8 rims for my 86 1st gen.

And I have two questions.

1) Do the 97 zq8's have to have the center hole area enlarged? some people have said no. How hard is it to check? If the wheels go on easy/hard etc.

2) What size rubber should I use to help keep rubbage, etc to a minimum.

I was thinking a P225 but some people have said thats not enough rubber for a 8" wide rim? Is the P235 ok and doesn't rub too bad?

97's will bolt right up w/no modifications. and to check it out jack up the truck take off a wheels and put the zq8 on, its that simple. and as far as tires go i was told 245/50 was a good size for the zq8's.

before we go on
1) 6 inch drop in back you will need to notch it dont notch to high because axle will hit bottom of bed. 2 inch is more than enough.
2) in front you will need to trim the bumpstops in half

now onto the rims
on that drop you can go with 225 50 16 front and 245 50 16 or 255 50 16 rear.

the 225 45 16 and 245 45 16 looked real good also low pro tire but with a 5 6 drop you should be ok with that size tire wont be to much gap. but the 225 50 16 and 245/255 50 16 are more price friendly

Hey Tony

is a 225 tire a safe width for a 8" rim like the ZQ8?


I think I have decided on a 225/50 or maybe a 225/55


I think I may keep all the tires the same size so I can rotate them easier.


Also the actual rims don't rub anything like tie rods, spindles, control arms etc right?



Thanks for the info!

yup yup i had 225 50 16 on my polished zq8s. if you want the same size all around go with a 225 55 16.

are you gonna lower the truck before you get new rims. if you do that it would help me a lot more to get the perfect tire size you want. orrr are you just putting the rims on now and lowering later?

Well I would like to do a 2/3 drop.

My truck is stock height right now.

I'd put the zq8's on this week and hopefully do the drop later.

I was thinking of some sort of belltech kit.

spindles/blocks etc.

Im not that knowledgeable in drop kits/methods etc

Thanks

Jeremy

those sizes fit on a 1st gen?

I've heard people say they rub on full lock turn with 235/55/16

Thats the reason I want to go with 225/55/16, to help keep the rubbing down to a minimum.


Thanks

Jeremy
