I'm about to buy new rims and tires for my 07 SUB. The are 22'', but i don't know, what size to get.
My option is 285x45 R22 or 305x45 R22
How's is effect a gas millage ?
Is anybody have some PIC with those sizes ?

Thx

 

It will affect gas mileage negatively due to the extra weight.

The 285s might work w/ a little heat gun treatment on the inner fender liners to gain some clearance. 305s probably not.

Of course it all depends on the wheel offset.

 

here is a Wheel Specifications Model- ACE-001
Size - 22x 9.5
Bolt Pattern -6 x 139.7 ( 6 x 5.5 )
Offset +25
Centerbore to fit -78.1mm

 

hmmm, im used tire calculator and here is a result:

Looks like, there look at the Overall diameter differences btw original 265x70R17 and 305x45R22. Looks like just a 1.20 inch. Is there possible rubbing ???

size 305x40R22 is same overall diameter than OEM 265x70R17.

 

It's the width that will rub. The stock offset for the OEM 20s is +31 mm.

 

I have 22x9.5 with a +30 offset with 305/45/22 and they do not rub. The overall diameter is a little bit taller so you'll loose minimal on the gas mileage but your speedo will be off by 3%....not a big deal.

For the original question....I recommend Continental Cross Contact. I have a 2nd set on now for my 07 Tahoe and the first set lasted 40K. Love the thread pattern and you can rotate all around.....they are non-directional.

Good luck

 

Thx dude
Well, ill go with 305x40 R22 which is the same overall diameter, so tacho should show same as original 265x70 R17.

About the tires:
Im looking for summer tires for those 22'' and for 17'' ill buy winter (snow) tires. Are they (Continental Cross Contact) quiet after 20-30k miles ?
Thx

 

Yes....very quiet.....just rotate them front to back then from corner to corner every 6-8k and they'll stay quiet and last awhile. Go to onlinetires.com .......I've ordered 6 sets of tires from them and they are reputable and cheeeeeeaaaaap

 

Is that yours Tahoe in your profile ??? If yes, may you post a pics ? I like yours rims
