22" rims, tire size question

[JoeMac40]

Ok, I have done a ton of research on this, and ready to pull the trigger on what size, but I wanted to get last minute opinions.

So I just bought some 22" rims for my X6M. 10" wide up front, 11" in the rear.

Factory front 275-40-20
Factory rear 315-35-20

So, the perfect sizes to get, to get about as close to factor circumference and aspect ratio between front and rear is:
Front - 285-30-22
Rear - 295-30-22

However, I want just a tad more tire for a little more rim protection, and a tad better ride. So I am thinking of the following sizes:

Front - 265-35-22
Rear - 315-30-22

These sizes keeps the front to rear ratio at less than 1% difference so no error codes or anything like that. However it will be giving me a tad over 2" full circumference (1" taller sidewall), but just over 2% bigger than factory. My speedo would not even be off by 2 mph.

So the question, if I do go the bigger set, which is more or less just 1 size up from factory, will I cause any real issues with gearing or computer stuff? I get it that my speedo will be off just a tad, but its not like I am putting dramatically bigger tires up, heck most could not even visually tell the difference.

I do realize I will loose some performance, which is fine, this is purely for the looks of it. If I need to go fast, or wintertime I will be putting the factory wheels back on, not like I am getting rid of them or anything.

Any real cons to going with the slightly bigger tires?

Anyone know?

Well I figured it out, if anyone ever checks this. 275-35-22 Front, 315-30-22 Rear will work perfectly and both the front and the back will look the same, and there is only a .44" of an inch front front to rear, so no issue with the AWD computer system. Also gives you 1" more protection vs. the factory size. Speedo will be off by 1.6 mph. Small price to pay for a little more protection for 22" wheels, look better, and ride better. Only bad part is very few tire manufactures make both sizes, I have found 3 brands. The 265-35 would also work for the fronts if you had to switch up brands, more make that size for sure. It just looks a little more stretched, and wont match the look of the rear that well.

The other options I mentioned would all work, its just this last set I found is perfect IMO. Keep in mind, all this research is based on 10" front and 11" rear. If you got 9" front and 11" rear, you would have a million more choices.
