I recommend a meditation session lying on your back and looking under your car, half-up on a curb - especially at the front tires at peak steering angles, both directions. I haven't gone to anything non-stock myself, but both the circumference of non-stock tires, and the section width, look pretty tight on my '17 Forester XT (stock 225/55-18). I think my tires are the same width & circ as yours. Going to 225/65 would mean you'd have a tire radius 11.5 mm larger (65% of 225 minus 60% of 225). If I recall what I saw correctly, a big radius tire looked prone to rub at the front of the front wheel well. a big section-width tire (e.g. 235mm) looked prone to rub the suspension arm at the back of the front wheel. My own speculative mod for my car is to go to 235/55-18 or 225/60-18 on 18x8 wheels; I still haven't drawn any final conclusions.Thinking of going to 225/65-17 Wildpeak Trails on my 19 Forester stock suspension. I've seen a lot of posts where people say this size fits, but looking for more detailed info. What about rub when driving offload, with decent load etc. Tough decision for me. Thanks for any input!
Hi,New Forester owner here, just purchased a 2021 Forester Premium. Need to add a winter wheel/tire.
17x7 48 offset OEM wheel
225/60R17 Briggstone ECOPIA 422 Plus (totally crap tire to be replace next summer)
Typically I would go minus 1, but some tire sites seem to think a 16” wheel is a no-go. I’m not sure why (maybe brake clearance?). So I started looking for 17” tires. I’m pretty partial to the Blizzaks. Had good luck on several vehicles. Unfortunately they don’t come in the stock size. I really don’t want to change circumference much at all. So then I start looking for slightly narrower, but with bigger ratio. Here is where I ended up.
17x7.5 40 offset Motegi MR139
215/65R17 Blizzak W90
Weight of this combo about the same as OEM
All the calculators seem to indicate it works, but with 7mm scrub.
- Anyone running a 16x7” wheel on a 2021 successfully (so I could go back to the minus 1 plan)? What offset?
- Does the small scrub difference on my proposed setup really matter on a Forester (handling)?
- Am I being stupid to give up the 10mm on tire width? (Some would say narrower is better in the snow anyway)
- What would be your go to setup on a 2021?
Thanks in advance for any help!
