Fitting 22's up front. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BaggedC10 · 10-16-2004, 10:58 PM

I have ART's Cool-Ride kit, stock X-member, no inner fenders, raised exhaust, and no heating/AC system. Will I have to tub the firewall to clear these wheels w/ say a 285/35/ZR22 tire? What size tires would you recommend? Thanks.

a 285 tire in front might be a bit much. personally i would go with a 265. i have had 265 35 22's fitted before, but i have no drop yet

.

i cant really answer that question because i dont know the and offset of the wheel.

Why do you want such a tall tires? That's like 29.85 in tall!!!! I "think" you will be alright at the firewall since you have no heater fan, but your going to be getting really close to the top of the inner fender....

I was just throwing that tire size "out there". I don't mind running rubber bands at all. Should I go w/ a 265/35/ZR22 tire or what?

**N2TRUX** · 10-17-2004, 11:33 PM

Oh, ok. I thought maybe because it was available in a specific tire you wanted to run. Although I don't recommend going with something as low pro as a 30 series tire, a 35 might be what you need.

Kumho makes a 265/35/22 and a 285/35/22 that sells for $217 and $243 respectivly. That might be a pretty good combo....

Thanks for the suggestion. Those should make for perfect f/r tire sizes. Now, if I could only make up my mind on which wheels to purchase.

you are going to have to trim the fenders and the hood to clear the tire. The inner fender almost has to come out, or you can cut most of it out...try going down to 30 series tires....

Anyone have pictures?

I knew I would have to modify the fenders after removing the inner fenders but trimming the hood?! From what I remember, I had enough room to clear 22's w/o much trouble.

A 265/35/22 is a little under 29" tall.I had this tire mounted on a 87 that was body dropped.It didn't hit the firewall but would hit the heater box.It will clear without the bd though.

**N2TRUX** · 10-18-2004, 02:27 PM

FabShop thanks for the input, and welcome to the forum. It's good to see someone involved with a shop posting on here...

it could be differant on the boxy bodystyle, but on a 67-72 22's will not fit without noching the hood.

I thought that was what you were reffering to. Because of the shape of the hood, and the height of the fenders, you do have to notch the inside of the hood.

It's not the same on 73-87's because the fenders are much taller. This tire isn't quit as tall as what we are talking about. It's closer to 27" tall but it gives you a good visual...

Thanks for the information. As Ken said, welcome to the forum.

loweredd · 10-18-2004, 06:26 PM

I have a 275/45/20, and it would hit the firewall if I didnt tub it. The drivers side is fine though?

fastbagged68 · 10-19-2004, 02:51 AM

It will rub- On my 63 suburban it is within 1/4" of hitting and my car is still going to come down another 1/2-1inch more. I also moved my crossmember up an inch. Run a 265-35-22. My tire on the front is a 245-40-20 BFG. I think it is 28.5" tall. If you are slamming the front to lay frame you should get alot of camber movement so your wheels will come in a decent amount. If you get the right offset it will clear your fenders.

Thanks guys.I have been looking at this forum for awhile but just decided to register the other day.I love giving info on suspension.

Stick around then. We could use a resident professional around here....

Shev · 10-29-2004, 05:19 PM

Okay...taking it one step further...I'm looking at running 265/35/22's on a 9.5 inch wide rim on my '88 burb and would like to run the same rim/tire combo on all 4 corners. What backspacing should I get knowing that in the near future the rockers will be on the ground?

You say the same tire combo. Do you mean wheel too? Are you trying to run a 9.5 on the front as well?

Shev · 10-30-2004, 02:26 AM

Yep....9.5 inch rim and 265/35/22 on all 4 corners with the rockers on the ground...I know it's possible, seen it done, just need to know what backspacing I need....

I wasn't saying it wasn't possible, I just wanted to be clear on what you were asking for. Let me see what I can find out...

6" bs will be fine.
