Need advice.... What wheels and tires???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1967K10 · 05-30-2003, 03:09 PM

Gents, I have a 67K10 and I am ready to change up the wheels and tires. I am also going to add a little lift in theprocess (3-4") and am curious to know what every one thinks would be a goood combo?

I don't want to have to use a step ladder to get up in her, so a 33" or 35" tire should be suffecient. Currently I have 16" wheels on it. Any pro's or con's on going to a 15" wheel? How wide of a wheel can I fet inside the fenders and still make corners without grinding off that expensive rubber?

Thanks! Heath

I think your best bet, would be to go to a few lift off-road shops that do that work and get there opinions. I think you would want a 16 or 17" rin with 33's a 7" suspension lift, not just a body lift

meathead95 · 05-30-2003, 08:17 PM

I would say with a 4" lift you wuld want 33's if your ever going to take it off road if not then 35's shoud be sufficient and a 15x8 or 10 wheel

1967K10 · 06-12-2003, 04:59 PM

Thanks guys, I think I have decided upon a set of 35's with a 15x10 wheel as I wont have her off road and my 406 will be more than capable of turning those 35's.

Does anyone think I can get away with 33's on my 72 K20 w/ a 2" suspension lift? They could be 33X10.50, not 12.50, if that is all that will fit...

I have 33" TSLs on 15"x10" rims. w/ 2" lift. The tires do not rub at all. Look at the pics in my sig link.

Jim,
Are they 33X12.50?
What about backspacing... did you have to do any thing fancy?

amstaff, they are the 33x12.5s non radials(load range D). The rims are off the shelf w/ 4" backspacing made by us wheel. In the pic the rims w/ the BFGs are American Racing white wagon wheels, they have 4.25" back spacing. The BFGs are 325/60R15 (about 31x12.5).

4" lift and 325 75 16 tires are perfect IMO. I would not do 15's anymore.

You WILL break the 12 bolt in the K10 with the 406 and 35" tires. I've broken the Jimmy's 6 times. Depending on my finances the next time it breaks, it will get a semi-floater 9.5" 14 bolt where I can keep my existing 6 lug 15" wheels, but I would prefer to upgrade to 8 lug FF in the back.

1969 GMC · 06-13-2003, 11:47 AM

other board members have told me that if you ever plan on upgrading to front disc brakes, you want to get 16" wheels. I would like to lift my truck a similar amount, but I plan to offroad it some. I am thinking perhaps a 4" lift, a body lift, and then 35's. I am also planning to install a newer dana 44 with disc brakes and open knuckles up front.

**JIMs70GMC** · 06-13-2003, 11:53 AM

Yep the 8 lug dana44 w/ disc will not clear 15" rims with out grinding the caliper, But I've read that you can use 1/2 ton calipers and not have to grind to fit 15" rims I believe I read that in Four Wheeler magazines project super-burb.
