February 17, 2005I am lifting my 99 GMC Sierra 6". I would like to put 35" tires on it, but I only have 3:73 gear. I'm worried about losing a lot of performance and gas mileage, so should I go with 33" tires instead?

February 17, 2005You will lose it. 4:10s or 4:56 would be best. You'll be ok though. I have 38"s on my 3:73's. But I have a diesel. It all depends on the motor. You'll lose some performance and fuel mileage but you'll be ok.
February 17, 2005I have 3.55 limited slip.. on 36" tires.. I would like gears, just cant afford them.. I might be going back down to 35" tires tho..
February 17, 2005I have 3.54's in my Dodge, and I run 35" MT/R's, I have the 360 (5.9L) but it still lugs quite a bit. If I had the $$ I would put some 4.10's or 4.56's in mine b/c I plan on lifting it and putting 36's or 38's on it.
Oh, mine will still run 110mph, it just takes longer to get there. And it uses alot of the fossil fuel that costs mucho dinero.
March 28, 2005I have 4.10s and 38's and it's a little sluggish but my 305 has no problem turning them over. my best friend has 3.42 gears and 33's and he has no problems what so ever and he gets great gas milage, but his brother has 35's and 4.56 gears and he is taching 3,000 rpm's at 55 mph which is killing his gas milage.
