1971 2wd conversion

Hey guys, I am new to the site and I could use a little help. I have a 71 K5 that has been converted to a 2wd. We have lowered the front using 3" drop spindles and a 5 inch flip kit to lower the rear around 5". The current tire wheel combo is 15 x 8 rally wheels 275/50/15 on the front and 295/50/15 on the rear with a 15 x 10 wheel. I am having some issues with rubbing on the rear and could use some suggestions.....
Can I get away with a smaller rear tire on the 10" rear wheel or should I move forward with a new wheel/tire combo?

thanks

I have a pic of a 275/60 0n a 10 on my LBT thread. Where's the rub? Out or in? Where you at in KCMO? Turns out there's a lot of us. Probably just a tad less BS on the rears.

Re: 1971 2wd conversion

Its at the shop now, and he called me saying the tires were rubbing on the outside. Im trying to decide if I can keep those wheels with maybe a 245 tire not sure if that will be enough difference

Re: 1971 2wd conversion

Backspace. Off the inside of the rim to the mount surface. A 245 will barely fit and look kinda silly on a 10. Unless the blazer rear is a bit wider, this is a proven combo unless you got some deeeeeeep barrel 10's. You need a hair more backspace, or lift the truck a tad or ach, I see you're a leafer. Rear is probably a tad wider than a coil truck... If its just barely, you could roll your inners back a bit, or get some stock 8's and run a 275/60. Are you still 6-lug? Hmmm. PM lolife99 he's a guru of the suspension, you may try this post again in the suspension forums. Welcome again!

Re: 1971 2wd conversion

A 275 will suck it in in and stand up more off the rim edge. might save your bacon, but if it's bad, new wheel time.

Re: 1971 2wd conversion

It has been converted to a 5 lug....so I could just buy 2 more 15x 8 rally's for the rear and get new tires all the way around. That would be the cheapest fix because I don't think buying new tires for rear is going to be enough. Or this would be a good excuse to buy a new set of wheels. If I went to an 18" x 8 wheel with a 255 tire that would also probably work.

Re: 1971 2wd conversion

10 would still be fine, just less backspace. Couple of companies do that. About 300 all in.

Wheel vintiques, among others. Wheelsmith, I think Stockton wheel is closed. Might have your current ones modded. Google 15x10 truck rally and go from there. Good luck! Do you do the cruise on the square?

Re: 1971 2wd conversion

OK men I found two options.
1) I can go with 15x 8 rally's all around and get a taller tire which should help my highway speeds

2) I found a 15 x 10 rally with the correct back spacing which will fit inside my fender well.

Is it worth sacrificing the look of the 10" wheel to get a taller tire on the 8" rim...for the sake of the ride, and lower rpm's on the highway??

what tire/wheel combo would be optimal??

Re: 1971 2wd conversion

I'm a fan of the deep barrel. That being said, if clearances prohibit that, I'd go to Liberty Bend and get 2 15x8's with 275's. cheapest way out. The last pages of the yeller thread show a 71 with 8" rallies with 255&275's. Have a look!
