Tire Weight Question?

[JayzDaMan]

Hey I was hoping someone could help me out. I installed some procomp all terrain XT 305/55/20 on my stock 20s on my 09 Silverado. I love the tires but never in my mind would I have guessed that they are 73lbs a piece! I can definately feel them on the truck. I've looked online and see that the Mickey Thompson ATZ in the same size are 66lbs. Does anyone know if I will notice the 7lbs differance between the two? Or am I just stuck with a heavy ass tire because all the tires I have looked at in this size are E rated.Thanks everyone.

The rule of thumb is for every pound of un-sprung weight is like taking off 10 pounds of sprung weight.

So by what yor saying is if I go with the lighter tire I would be saving 70lbs at each wheel?Brake performance would be better too?

Yes on both!

Wow! Thanks. I never would have guessed that it would be that much of a differance. So I guess I'm looking for a lighter tire!

this is why i want my next set of tires to be P-Rated 275/60/20s....they wont be as bada$$ as my 305/55/20 mickey thompsons, but ill save a good 20+ lbs PER tire!

 

damn things are wearing too good though... looks like it'll be another year before i can consider a new set, and the ATZs will still probably have a ton of tread so ill just throw them on craigslist.

I was waiting for you to chime in Matt! I know that you are the suspension and tire guy around here! LOL! So do you think it would be worth it to talk nice to my tire guy and see if I can exchange these procomps for a lighter tire such as the Mickey Thompson ATZ? I would like to find a C or D rated tire but no such luck in my 305/55/20! Thanks.

honestly, i dont think 7 lbs per tire is going to be a big enough difference to justify spending a considerable amount of money on for the change. if the weight really bothers you, you're going to want to jump back to a P-Rated tire (seriously, D and E rated tires are extreme overkill for these trucks....C is a good idea if you tow heavy loads daily; otherwise, theres nothing wrong with a P rated tire in terms of load capacity.... they're just not as robust for offroading)

 

with that said... if your tire guy can get you into a set of ATZs with little out of pocket expense....why not? save a few lbs per tire... even if you dont "feel" a difference you'll have some of the best looking tires on the market =)
