I decided to upgrade my Tires and Rims. I was looking for a set up that would be lighter than the originals and I also wanted to incorporate a Full Size Spare for safety concerns and also to be used within my Tire Rotation Schedule to increase longevity of the whole set. My original combo weighed 48 lbs and this is with 35k Miles on them. I went on www.tirerack.com and found the reviews of the Continental PURECONTACT LS Tires to be outstanding compared with the Original Pro Contact TX. Both of these tires weigh 21 lbs New so there was no gain or loss with my choice of tires. Then I searched for rims looking for anything that would be under 27-ish lbs to keep me lighter than the originals and found a sweet set of O.Z. Hyper GT HLT rims that weighed 17.85 lbs EACH ! so I figured these babies would weigh in under 40 lbs for a savings of approximately 32 lbs for the 4 being replaced. Long story short, the 5 tires and rims total weight was 205 lbs @ 41 lbs each while the 4 originals weighed 192 lbs @ 48 lbs each so now I've got a set up with 5 tires / rims that only weighs 13 lbs more than the Original 4 tires / rims. The ride is so much quieter and smoother with the new tires and they're also "Eco Tires" so I have not noticed and drop off in MPG's yet. Here's a few Pics.
