I just bought some commuting rims and am contemplating buying new LRR tires or just swapping the stock Eagle RS-A's on... Anyone got any helpful opinions?

 

I do not think that you will see a big increase in MPG just by chaining out rims & tires. People say that if you install a CAI you get better MPG. The only real way to get the best MPG is to drive 55 MPH on the HWY and 35 in the city ;)

Cheers

 

Rims are tires have a dramatic effect on MPG... Since most hybrids come with LRR, I was just wondering if we can see an improvement from our stock Eagle RS-As. I found a thread where a guy went from LRR tires to Eagle RS-A and claimed he lost 10% to 15% mpg. If the inverse is true, can we expect to see a 10% to 15% improvement using LRR tires?
