Hello, I just bought a new 22' LS Manual Black in color from a dealer in Jacksonville, Fl (Dec 10). I am in South Georgia and on my first tank I got 40.5 mpg figured at the pump 7.8 gal at 316 miles. I wanted to get wheels and tires and wanted to make sure it will fit. I am leaving suspension stock. I was going to go with the setup that SparkGuy026 has 195/60/15 bfg radial t/a with advanti racing 15x7 wheels (judging by the picture). I love the white letters out! I had a few questions if I may. The tire will be 1.2 inches taller and half inch wider and 4 lbs more, the wheel will be half inch wider and 13 lbs less. So tire wheel and tire weight goes from 40 lbs to 31 lbs. My theory is if I can get my rpm down some it might be better for longevity and better highway mpg. I do mostly hwy and South Georgia is mostly flat with very slight hills.
Does anybody have any rub/scrub at all?
Does anybody have more/less/same mpg after putting on bigger tire but lighter aluminum wheels?
Better ride/less road noise?
How much less rpm with larger tires? approximately?
Will the mileage be off? (I know the speedo will be)
Thanks for any advice

Why? You're not gaining anything but expense and headache. This car just doesn't have room for more tire and wheel. It's a budget econobox - save your $$.
Yes, everything will be off.

If you want a dress up, get a set of wheels you can mount the stock tires to. When you wear those out see what other options there might be.
Would be nice if there was a Michelin replacement - quieter and smoother.

I sold all four hubcaps and three of the stock steel wheels on ebay, so the cost for a set of alloys was about half paid for. Swapped the kumhos over, and got one more tire for a full-sized spare for when we travel with the car. The donut spare is fine for around town, but wouldn't want to go very far or very fast with it.

Anyway...sorry I don't have more.
