275/45R20 on front?

[cjohnson6772]

Will a 275/45R20 fit on the front of a 72 C10?

[bob arrington]

went and looked at mine, a 71 C20 they are 265/50/20, I've lowered it 3" on the front and 4" on the rear, dont know if it will give you a place to start , but they're not rubbing and fit inside the fenderwell, before I lowered it there was 3" clearance front and 4" rear. hope this helps

Thank you for taking the time to check! 265/50R20 is actually taller than what I had planned so I should be good if yours aren't rubbing on the front.

I didn't think to ask before, but do you still have stock front wheel tubs?

I run a 255 50.20 on a 5.25 backpacking 8" rim. Back spacing is key to prevent rubbing

everyrthing still stock, im running 2004 chevy 8lug wheel offsets and actually had to space the rears with 1.5 spacers to get them to fill the wheel well better due to the different axle width front to rear. The only issue after I lowered it the 3" and 4" was that the top two front fenderwell bolts rubbed on bumps and turns. Removed them and got new shocks, no more rubbing. I had purchased the rear tubs, but sold them when they werent needed

72Mario. I'm looking at 275/45R20 on 20x8.5 or 20x10s. I would prefer 20x10s if they will fit. Looking at American Racing VN506 or VN215 if possible. What is minimum offset that you would think would fit on the front with a 3/5 drop?

[cjohnson6772]

Bump back to the top for more replies hopefully. I'm planning to get 275/45R20s for the front and rear on 0mm or 6mm offset depending on which wheels I go with. Probably going to only lower 2.5" with spindles. Maybe lower about 4" in the rear.

Front Wheels are 20x8.5 - Offset: -6 mm
Tires are 235R/45-20

No issues with rubbing.
Truck is lowered 4 inches.

I think the 275 will be too wide for the front. My 235 are as wide as I can see fitting without issues.
I am using the 235'S WITH /20x9.5 wheels on the back. 0 offset, they fit fine there. But are still close.

265/45R20 on 20x8.5 with 0 offset. Clears. Tried a 10” front wheel and it rubbed the lower control arm turning with 0 offset. Wheel spacer would help but then the tire would rub the inner fender

275/45R20 would work on this wheel and be ok. I had to move my lower shock mount cause it rubbed the tire but I also have porterbuilt control arms

This! So much this! Love the truck and stance. Do you mind sharing which PB control arms you have (forward and/or narrowed)? Also, what are the lowering specs on the truck? I am not looking to go very low and your truck looks about right for my tastes.

1” forward with 2” modular drop spindles, 2” drop spring

Rear is a No Limit 4 link. No idea on the drop. Just adjusted the coilovers until it was ~1/2” higher in the rear

Thanks man. I found your build thread by the way. Awesome truck.
