Tire Size & MPG
I know the MPG "should" be a minor change (whether + or -) but what do you guys think?
Stock tires are:
225 45 19 @ 27 lbs each
245 40 19 @ 30 lbs each
Replacement tires are:
245 40 19 @ 26 lbs each
275 35 19 @ 29 lbs each
I know that going wider will result in more rotational mass and friction, thus expending more gas but would the decrease in weight (as little as they are) cancel out any negative effects of going wider? This is with the stock rims too. Once my tires need replacing, I'll probably buy some Yokohama S Drives because:
1. Better tread wear (300 vs. 140)
2. Better traction in all aspects (wet, dry)
3. I'll end up saving a total of $178 total on tires vs. stock replacements
4. These tires weigh 1 lbs less
What do you guys think?

How does 245 40 19 have 2 different weight?

The tread wear rating differs between brands, so its hard to compare.. But generally it should yield better tread wear with a higher rating.
take a look at http://www.tirerack.com/images/tires...y_f1_gs_ds.pdf
For tire comparisons, surprisingly, the stockers scored 9th place, which isn't so good. I didn't see the Yokohama s-drives on there though.
I would assume that it would balance itself out with wider tires but less weight.

I looked up the specs again but it seems like the stock tires compared to the S Drives has a little higher rating for steering response and dry traction (not too big of a difference). Wet traction the S Drives are higher.
Although the tread rating differs from brands, the number was more than double the stock tread rating. I'm leaning towards the S-Drives.

if you go for thread wear numbers traction not so good....the lower the thread wear number the softer the tire.....i like softer tires anyway my opinion and 2cents
