found good deal on some local wheels, but after hours of searching and reading I can't seem to find the info I'm looking for....

Wheels are 18x9.5+24 and 18x10.5+22. I will be running feed fenders (+25) front and rear and I'm looking for the widest tire I can fit. Would really like to do a 295-315 in the rear if possible with that offset.

Any help would be greatly appreciated...
