2 door Tahoe Tire size HELP!!!!

[2boosted]

Welcome to the site.

I'll assume is a 4WD.

To fit those tires under the truck you'll need at least 2-2.5" levelling kit. You "can get away" pumping up your torsion bars. But you"ll end with a crappy ride. Even with the levelling kit (torsion keys) you'll end up with a crappy ride. Try to purchase a good levelling kit that comes with Shocks extensions or buy better shocks for the front.

Now IMHO, your Tahoe been stock, I'll recommend 305/50/20. Those are almost 1.2" lower than the ones you want. A good Alignment Job and a turn to the torsion bar bolt will be enough.
Also the kind of tire you selected for the stock suv is really aggressive. I recommend some Cooper Zeon LTX. Those will give the mean off-road look and capabilities, with great on road manners.

Thing is, the tires you select are great for off-road, and where those tires can GO, your stock Suv suspension may NOT

Just my opinion, hope it helps.
