It's looking like I'm going to need tires soon as my right rear tire is wearing faster than the left. Guessing an alignment is in order as well and since I replace tires in pairs I'll be buying 2 new tires and have a few questions on types and size.

1. I am currently running 195-60-15 and am thinking about getting narrower ones; 175-65-15 are 0.2" shorter than the 195-60s. Wondering if 175s on a 6" wide wheel are too narrow and/or MPG beneficial? I'd like to consider safety as well, I don't drive like a crazy person but I want to be safe in all weather conditions and will take a small MPG hit to retain safety.

2. LRR tires in both sizes seem to start around $80/each on tirerack.com and there are tires $20 less that aren't. Will LRR tires pay for themselves in savings? What are some realistic gains to be had from these tires?

For reference, with my taller geared trans I cruise at 2,000rpm @ 60mph. I think that it is about at the bottom of my eco range and think that spinning the engine a little more might be beneficial for my 95% highway commute. Thinking that a little more rpm might keep the engine from loading so much while climbing all the overpasses I deal with and might net a small mpg gain, or at least not take a hit (hopefully).

Thanks,
