I am thinking of these BBSrims for my winter setup.Would the Nokian 275/45 R20 fit these rims?

jimrhit

I have a set of Nokian Hakka R2 SUV in 275/50/20 that I used on my SRT Jeep last winter. I've sold the Jeep and have 21" snows for my Q7.

Spectacular snow tires, made the Jeep a blast to drive. If anyone is interested, please message me. They have 3,099 miles on them, per the receipts from Discount tire when I mounted and dismounted them. Located in Detroit

Thanks
Jim

Almost certainly, but you would have to look up the rim width to be sure, and then make sure it falls within the tire's recommended rim width. But I am not sure why you would get a smaller diameter tire when the 255/50R20 is the correct diameter. You won't find too many people who try to have a wider winter tire either.

As discussed on other threads, the overall rolling diameter between a 255/50/20 and 275/45/20 is so miniscule that you will not notice anything in daily driving and hardly will the car. There will be less than 1 mph of speedometer error at 70mph crusing speeds when running a 275/45/20 versus stock rolling diamater, which amounts to no more than .2-.4 of an inch! That's not much when we're talking about a 30" tire. So unless you're oddly obsessive about getting the exact real-time mpgs recorded on Fuelly, or long-term stats and exact odometer recording on some database, it's not going to make much difference for all intents and purposes.

On the other hand there can be plenty of perfectly sound reasons to go with a wider winter tire, and in this specific case, a 275/45/20 over a 255/50/20...
1) you want the highest possible load rating that the 275 affords over the 255, for heavy hauling, towing a trailer, etc. (applies to me)
2) you have a wide aftermarket wheel that will not accomodate narrower section width tires. Example: you have your eye on a certain wheel design for winter use that happens to be 9.5" wide, which is beyond the typical recommended rim widths for most 255/50/20 tires.
3) you want more rim protection from a wider tire, so that your wife/husband who still insists on parallel parking on curbside city streets by "feel" is less likely to inflict curb rash damage. (this applies to me)
4) you live in an area where it doesn't snow all that much but it does have very cold winters, so you want the benefit of a good winter tire compound but would like to maximize dry performance and braking in the cold winters by retaining a larger contact patch. While a narrower tire will offer better traction and directional bite in deep snow, it does so at the expense of a smaller contact patch that sacrifices braking performance and lateral grip when the roads are dry in the winter. Here's where having wider winter tires can shine. (this applies to me)
5) you just like the "look" of wider tires. Nothing wrong with this. It's a personal decision that only you should make and have to live with.

The truth is there is no single right answer as to which is best, so no need to steer others in the same direction as you. If you live in a region that gets lots of snow, a rural area where roads are poorly maintained and seldom plowed when it snows, then perhaps a narrower section width tire is best. If you're like me and live in a place like Chicago where although it gets bitter cold, we basically had only 2 days of light snow all of last winter and only a few flurry dustings here and there that never accumulated, then you'll probably start weighing the benefits of wider section width tires and what they can do for you.

That is true, so sizes to consider are:

285/45R20 (exact diam)

255/50R20 (exact diam - load 2271 lbs per tire (9084 lbs total))

275/45R20 (slightly less tall - 0.9 mph off at 70 mph - odometer 1.3% off - load 2337 lbs per tire).

265/50R20 (slightly more tall - 0.7 mph off at 70 mph - odometer 1% off).

And I don't even care about the 0.9 mph off on the speedo at 70. If there was a way to calibrate the odometer to match, I would be 100% fine with it.

LarryV - My wife got a new Q7 recently and we have not purchased winter wheels/tires YET. She had Pirelli Winter Scorpions on her Odyssey, which I wasn't excited about when we bought them, but they turned out to be very good for suburban Chicago winters. Are the Hakka's quiet at highway speed and are you able to push the Q7 a bit in dry corners?

Also, which SQ5/Q5 wheel did you end-up using??

I went 265/50/20 on my R2 SUVs. I’ll take 1% error to have the higher load rating.

It won't be a popular decision but I generally try and use my stock wheels for winters since I have aftermarket summers. Going with 265/45R21 Nokian R2 SUV tires. Love Nokians as this will be my 6th set. Stock size of 285/40R21 in the Hakka 9 are currently unavailable in NA. Tires arrive this week and hopefully so does the car.

I swapped to a smaller aftermarket 19" rim for the winter, and was able to install Nokian Hakka R2 SUV in that size.

Has anyone bought Nokians online?My local Nokian dealer gave me a run around and after 3 weeks and Multiple phone calls told me that they are not in stock and he cant promise a set until next year.
