I have stock rims with new tires at stock size: 225/55R18. I want to try a smaller diameter for winter tires, and swap them out. Can I go to 16"? I may want to use the new wheels during the warm seasons to get less jarring ride. If you've gone down to 16, how was the ride controlled, and did you wish that you did it sooner? What PSI do you run?

I find that the 18's are comfortable at 31 psi and below. But, the ride gets jittery at a higher pressure than that. I'm using Yokohama YK740 GTX. I tried 235/55R18's, of the same Yoko model for a month, and and it affected mileage, acceleration (initial throttle response the most) and noise negatively, but it was a significantly less bouncy ride. Could go to 17", but would try 16" if I could. Discount Tire / Subaru dealer couldn't tell me if I could do it or not -- just that it was not recommended as per their notes. Not sure if it's just the XT's that don't have the clearance. I see other posts that non-touring models seem to be able to take the 16's.

Otherwise, I do like the summer/rainy weather performance of the Yokohama's. Went over the mountains a few times the past few months, and the vehicle felt confident and got good mileage.

Thanks

Last time I checked '15 Touring trim does not include larger brakes.

You're fine to use 16" wheels.

There is nothing about Yokohamas that makes them a luxury ride--look at Michelins in the models used on luxury cars in whatever size you buy and you'd be surprised at the world of difference they make even in your stock size. Buy the tire models that Lexus and Mercedes use, not some Discount Tire house brand model.

The largest wheel size on non-trucks was 15" for many, many years and handling and ride was just fine. I'm a bicyclist and know that there is a huge difference between a $20 Asian tire and a $80 Continental tire (400 threads per inch, made in Germany) even when you are looking at 25mm wide tires inflated to 100 lbs. Cheap tires ride like cheap tires. Buy good tires designed for a good ride and you get a good ride.

Continental makes the best bike tires and Michelin makes the best car tires.

Thanks. I’ve used Michelin’s in the past on cars, and they’ve been fine. In this case, I’m looking at using a 16” rim for snow tires, and if that seems to improve the ride, then consider a 16” all season.

Since you know about Michelin’s, what do you think about the Primacy Tour (V rated) vs CrossClimate2 (H)?

Edit, more pressing: Michelin X-Ice snows vs blizzaks. Thanks.
