I changed my stock, 17" staggered set up for an AMG 18" staggered set up.

I want to use the stock 17" staggered set up with winter tires. Front is 225 45R 17, rears are 245 40R 17.

I can't find a matching set from various manufacturers. They either do one size and not both.

Is there a problem if I go to 245 45R 17 on the rears? That size is much easier to find that 245 40R 17.

Why not just go with 225/45/17 all around? Having a wider tire in the snow is not an advantage.

I don't want to buy 2 new rear rims to match the width of the fronts. 225/45 may be too narrow a tire for the wider rear rims I think.

I as well would go 225/45 17 all around. I think you will get better winter performance with a tire not as wide.

I have 30 years experience driving in Canadian winters. Staggered or not, will not make a difference to me. I can drive fine on ****ty all seasons since I know how to drive in the winter so a staggered winter set up won't make one difference over a non staggered winter set up.

I want to know if going to a 245 rear instead of a stock 240 will adversely affect anything.

Yes. F&R diameters need to match within a couple of %. Otherwise you get ESP/ABS errors. You have to do the math.

You can use a 225/45x17 all around including rear on staggered wheel set up. Specs of the tires also fit 8.5" wide rear wheels as well.

Tire rack has Yokohama Ice Guars which are available in staggered setup for 17" wheels...that's what I run. Downside is they are noisy

Perfect and thanks. That is good news since I was unsure if the rear rims would be too wide or not for a 225 45R 17. Finding a proper staggered set up is near impossible since either one size is discontinued and the other size still available or each size is from different manufacturers. I looked at the Ice Guards up here but only available in a T speed rating. I am after a min of an H rated tire.

Your driving skill means nothing when you hit black ice or the car in front of you, which has snows, slams on the brakes and you can't stop with your ***** all seasons.

Yes, it will fit, but I've seen photos, and it just looks hella weird when the tire is trying to fit around the wider rim.

Colin G

I may be stuck with the T rated Yokohamas then. Only tires I can find in the sizes I need front and rear that will fit the 17" wheels that came stock with my car.

Are you referring to experience looking at a 225 on a 8.5" rim? Plenty of pics online showing 225's on 8.5 in wide wheels as BMW's also have the same challenge. Doesn't look weird to me.


225 on 8" LEFT. 225 on 8.5" wheel RIGHT

T rating should be more than sufficient enough. that's 190km/h.
Most dedicated winter tires come in S,T,U speed rating anyways.

superangrypenguin

Thanks. The photo I saw was directly at the rim/wheel, and what I noticed was that because the rim is wider, there's less sidewall protection for the rim. I have no idea how better to explain what I'm trying to convey, sorry.

On the 8" rim, the sidewall sticks out more. On the 8.5" rim, because the tire has to go around a fatter rim, there's less of a sidewall protrusion and thus the rim lip can be more easily damaged. Would you agree? Any chance you have a photo of the sidewall of the 225 45 17 tire on the 8.5" rim?

I agree a little more stretched.....I was curious myself as I wouldn't want to stretched look like in the Stance scene. I also think it be pends on the tire and the "rim protector " molded into some tires. Some show it more than others. Personally for me, I like a square set up for winter tires to rotate and get more life out of em.

superangrypenguin

As would I, and in my case, (not that it has anything to do with winter tires), I really want to try out the Toyo Versado Noir, and that only comes in 225 45 17 and not 245 40 17...

BAH, GAK, I don't know what to do.

Colin G

I would prefer that also but I don't want to buy new rims for the rear. I want to use the stock staggered set up to avoid buying two new rear rims or a set of 4 steel rims. I am not using my stock 17" setup so I want to turn them into Winter wheels.

If you want to go 225 all around, that's fine but also there is absolutely no problem driving with staggered setup during the winter.

This is my 6th winter with 225 front and 255 rear on 18" wheels and there is absolutely NO trouble. Believe me, I've been out on the road on numerous snowy days for 6 winters. Just buy good winter tires, stay away from deep snow and you are good. Narrow rear tires ruin the looks of the car and I wouldn't sacrifice that for 225 all around tire setup with mere benefits (if any at all).
