yes they would I used to have 31s on my 94 and they fit just fine they just rubbed a little
35" Tires will require a 6" suspension lift to clear with no rubbing. A cheaper alternative is a 3" body lift, and 33" tires, although not as appealing.
No
Yes they will. I have 305 24" wheels for my 01 Tahoe. They fit well.
The Chevrolet Silverado has been in production for a number of years. The 2014 Chevrolet Silverado 1500 (2WD Crew Cab) can be fitted with 17 through 22 inch tires. These will require the use custom wheel and tire packages.
brakes are to big to fit 15 inch rims
Yes
What is the biggest tire to be used with a 2002 Chevy silverado 4x4 (16in rims) with a three inch body lift? I really want 305's but jcwhitney said to go with a 285. Could i just trim the plastic?
1 inch
The Rims will fit as long as they are the same number of studs and puting 17 inch rims on will not screw up your speedo as long as the tires you use have the same outside diamiter. If they are the tires that came with the original 2007 silverado they will be the same outside diamiter as your 16" wheels and tires You can also adjust for larger tires on the speedometer with a hypertech controller.
If it's a 4 wheel drive, you will need to crank the torsion bars to get them to fit the front. If it is a 2 wheel drive, you will need a lift kit. A 3" body lift or a 4" suspension lift should do the trick.
you'll need 6" + some trimming to fit 35's.
