Use it or loose it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have these 15x10 wheels which have a serious negative offset (not sure if this is the correct terminology). The back of it says offset -50? I included pictures with measurements. The front measures is 6-3/4" and the rear is 3-1/2".
I have 33x12.50's and 15x8 ralley's on my 71 K10 with a 4" lift.
I like the looks of the ralley's but I'm not sure if 8" is wide enough for my tires.
1- Are the 15x8's wide enough for the 33x12.50 tires?
2- Would you use wheels with this offset? Why not?
3- Can you post pics of something similar that shows how much they stick out?

Should I use them or loose them?

Thanks! I'm posting this on the 4x4 board as well.

My Blazer had 8 inch wide rims on it with 35x12.50x15 tires when i got it. I put on a set that are the same size tire but the rims a wider. I havent ever measured the ones that are on there but heres a pic of them.

Here is a pic of the ones that came on the truck the front tire is an oddball that didnt match the rest

Those wide rims don't look bad at all on your truck. What kind of lift do you have? Any problem rubbing on tight turns? Notice any difference in handling?

LudwigTheMad · 08-23-2003, 01:20 PM

I have a similar set of Weld alm. rims....the 3 1/2 backspacing is to keep the corect backspacing for cars/trucks that originally had 7" rims (used alot on the 60's Vette's) so as long as you have the clearince up down you should be ok.

your not suposed to put anything wider that 10.5 on 7's and 11.5 on 8's, the reason is that you push the seal on the rim out and make it weaker, so if you do it, watch the big bumps......

i only drove it on the road once with the narrow rims so i really didnt notice if it handled different or not. All i have to compare it to is my daily driver which is a 03 Hyundai accent but i think for its age and size it handles pretty good. I dont know what kind of lift is in it I think its around 6 inches worth and i have not had any problems with rubbing but i have not had it off road where it would see some twisting. BTW if you are thinking of selling them rims i kinda like them.

Blue,
I'll try to test fit them with tires sometime next week, unless I get a lot of advise not to use them. I am waiting for a friend who said will sell me his 33's. I'd rather not remove the tires I have on right now. I'll let you know if I decide to get rid of them. They come with rear caps and front 4x4 caps.
