Changing tire sizes?

[Galaxy]

Michelin CrossClimate SUV is available in 225 -60 R18. It is rated as an all season tire that goes beyond M+S with the Snowflake symbol.

Struggling to wrap my head around why you would want to put truck tires with a highway tread on an Outback.  In terms of grip, a highway tread M+S truck tire won't really perform any better than an M+S all-season passenger tire.  They use similar tread patterns, so it's not like you get a more open, grabbier tread pattern.  What the truck tire gets you is a more heavily reinforced casing with extra radial belts designed to deal with heavier loads that a truck or cargo van may carry.  This also typically results in a stiffer tire that will compromise ride quality on a passenger vehicle.  You also tend to pay more for the higher load rated construction.  Unless you are hauling/towing, I'd stick with a passenger tire.

Agreed, any all seasons in the stock size should do.

I like heavy truck tires because I can blow through potholes drift into curbs without being put out.

Speaking of truck tires, I need to replace the tires on Blue. I'm thinking 700x15LT 6 ply commercial tires like the ones it came with.

I bet you can find some nice bias ply trailer tires with whit walls.

How the hell do I know what my rim size and offset are?

Offset doesn't matter if you're keeping the same wheels. You can get the wheel size from that site too.

I feel like the added width + aggressive truck tire is really going to destroy fuel economy. I mean, it doesn't really snow in Seattle, and how often do you really go up to ski in the mountains?

There's nothing particularly aggressive about a highway tread.  They're designed to give better fuel economy than an A/T tire for people who don't got off road with their trucks.  Basically the type of tire you get on a cargo van like a full size Transit.

Got the CrossClimates ordered for 185 a tire from Discount Tire Co. Not bad

TireRack wanted $215 per tire.

[CaminoRacer]

Discount Tire is the only tire shop that I like as much as I like Tire Rack.

Maybe it's just the fact that they're new, but my initial impression of the CrossClimates is that they drive really nicely. The tires bite in hard and quickly when I make a turn. Previously, there was a certain amount of scrubbing before the car would start to change direction.

[Laconian]

Lovely, lovely tires. Oh boy. Very quiet on the freeway, with almost scarily low rolling resistance. Tire roar is gone, replaced by wind buffeting. I can't wait to rack up some a statistically significant number of miles so that I can compare average fuel economy with the previous tires.

Takes about half a year to really see with the season change and gas blend switching

Hopefully you see an improvement

I am absolutely loving getting 30-40% better gas mileage in the TLX... to the point that I'm hesitant to throw the 20s from the Optima on

[Laconian]

Oh, you got a TLX? Nice

Good to hear the crossclimates worked.

I'm completely stump on what to put on the Giulia when the time comes. Really no other choice if I stay with an all season run flat.  While I drove the RX8 with no spare and no run flats, the though of a flat on my daily commute is frightening with high speeds and no real shoulder to the highway.  Tons of choices for dedicated summer and winter tires though.

R compound. Resistance is futile. Mileage is irrelevant. Weather is irrelevant

Get some real tires and a fix a flat kit
