I'm overwhelmed by the numbers!

Here's what I want, maybe some of you can point me in the right direction.

I want the overall diameter to remain the same - no larger. So that my speedo and everything are still calibrated, and I do not lose any torque. However I do want a more aggressive tire for off road use.

I see not many are available at all in this tire size, so I started considering putting 15" wheels on the subie, so that I could put a real pair of BFG all terrains on or something. Is this possible?

Do I just need to do more homework?

For example... If I were to find 16" wheels that fit, and put 215 70 16 tires on, so that the overall diameter is still 28 inches, is it as simple as that? How do I know which 16" wheels I can use, though?

Thank you for your help and sorry for my ignorance.

Yokohoma Geolandar A/T-S tires come in your stock size (225/60/17) and that is what I got as a full size spare to go with my XT.

See this post for pictures of mine (on XT rims and 17" spare). So far I have been quite happy with them, but have only had about 2 weeks with them. No rain, snow, or mud to test in yet. I have been happy with the performance on gravel, where I do not seem to slide around in situations I would have on the stockers.

I plan to test them off road at the http://www.subaruforester.org/vbull...-soft-road-meet-2014-bridgeport-texas-282650/

You can experiment here to see what size you should go with if you downsize rims. http://tire-size-conversion.com/ Notice a 16" rim would require a 225/66/16 which means the closest would be 225/65/16.

Good call, thanks, those really fit the bill and make this a lot more simple, thank you.


Does anybody have experience with these?

I'm reading the reviews and they're very mixed... People either love or hate them. A lot of people are saying they're worthless after 40k miles of wear, balance issues, poor traction....

I hate reading reviews because there's bad for everything, but want to make sure these don't have issues.

They should be good for you, and you won't have to spend money on new rims.

Here is another thread, and I realized I did not link to my post like I had thought.

Thanks dude!

Another quick question...


225/60/17 is the same as the stock size tire, right? So there would be no change in tire diameter, speedometer readings, stuff like that, right?

225/60/17 IS stock size.

Personally, I like this tire/wheel calculator a little more because it's a tad bit more in depth..

http://www.rimsntires.com/specspro.jsp

Enter in your stock tire size which is 225/60/17
Enter your stock wheel size which is 17x7
then enter your stock wheel offset which is +48

If, for example you want to run 16" wheels you can select that size and experiment with tire sizes that are similar in overall diameter to see what the difference in speedo would be. Make absolute sure you know the offsets of the wheels you're looking at though. It'll tell you if your too close to the suspension or too far out from the fender. It's okay if you're not exactly the same size as stock, you won't hurt anything but it's a good idea to understand your changes.
