4/6 Drop Tire size.

[BalancedBore]

Hey everyone, I am fixing to be doing a 4/6 drop on a 1997 Chevy C1500 4.3. I am planing on going with with American Racing Toque Thrust 20x8 in the front and 20x10 in the rear. What would be the max tire size I could go with that has little to no rubbing for the front and back.

245/40 front
275/40 rear

Have that size front tire on my tahoe with a 5/7 drop. Does rub on the outer portion of my A Arm when turned full lock. 275/45 (wanted a little more side wall) on the rear & no rubbing with them.

 

[sewlow]

255/45's & 295/40's on a 4/7. 8.5'" & 10" 20's. Virtually the same sidewall heights.
Close enough to the original 235/75-15's diameter that they do not mess with the speedo's accuracy.
Toyo Proxes STII. Not made anymore. Replaced by Proxes STIII's.
Fender lips rolled Fr/Rr, although the rears didn't really need to be done.
The fronts do rub at the lower rear of the fender well, but only on hard suspension compressions.
My 275/60-15's, a much shorter tire, also rub in the same spot.
It makes a terrible 'bzzzttt' noise when that happens but the tires never suffered any damage from that over their lifetime of about 40,000+ miles.
Only damage to the truck is that some paint gets removed where they rub. Easily touched up with a quick squirt of some 'Bumper Black' or 'Hot Rod Black' aerosol.

Apologies, but I have no idea. I told the guy what I had, what had been done to it & what I wanted. He handled the rest.
The 295's do tuck @ 7", though.
Sig pic's @ 6".
This is @ 7".

That's a lot of wheel and tire under there! Do you know the brand of the wheels? That's great that you can get 295s tucked in the back. I'm trying to get a better fitment on my truck, and that info would be helpful. Thx!

They look like Torq Thrusts...
