Rim & Tire Size Help:

[ridingreiss16]

Please help!
I was just told you cant lower 15x8 rally rims in the front because of the spindle clearance and front tires rubbing, so I have to go to 15x7's in the front. Thinking about just selling the rims and going to Weld Racing. If I do 15x7 Weld Racing in the front, what is the biggest back rim I can do in the back and the fattest tire I can go without tubing the bed? Truck is almost finished painted and and I need the rims/tires ASAP. Thanks!

You can lower a c10 with 8in rallys. I just lowered my 78 yesterday with rallys. I used CPP 2.5in drop spindles(1.25in rotors) and cut one round off the front springs...no rubbing issues at all. I lowered my 82 with Mcgaughys 2.5in drop spindles(1in rotors) with the same wheels but I did have to grind a little bit off the lower leading edge of the lower control arm but that was it.

If you decide to go with Weld Wheels a 15x10 with 5.5in backspace will be perfect.

So if I did 15x10 with 5.5in back spacing Weld Racing Rims in the rear then I did a flip kit it wouldnt rub at all? Then do 15x7 in the front Weld Rims I can do drop spindles with out any grinding?

Yes with 295/50x15 tires. Below are pics with 5in backspace and the clearance is 1/4in on the outside and 1in on the inside. As long as you have 4in or less backspace on the front you should be fine but I do know a guy with 15x6 Welds that had to grind slightly on the caliper but he has 3in drop spindles.

Sorry for so many questions im 16 and trying to restore my c10, I just got my truck back from paint today, Im just going to stick with the Rally Rims. If I get the drop spindles and the flip kit as long as 1.25 rotors would it be a possibility I could come to you and pay you to help me? I have no experience in suspension work or lowering it

[J Knight]

Well, you can bring it by so I can check out the condition of the suspension and see what you need to get it where you want it and we'll take it from there.

Okay sounds good, I will be okay though putting 15x8 rally's all around the truck at stock height for now? Then once you get a chance and are you're free I can come to you with the rally's on stock height and see what lowering I will need? I appreciate all the help, thank you very much!
