Be careful of the ply rating of the 8.25s. Most 7.50-20 were 8 or 10 ply tyres, while the 8.25s are usually 10, 12, or 14 ply. A rough ride will be the result, shaking you to bits.
Are you running duals on the rear axle? Unless your rims have the correct offset for 8.25s, when loaded the tyres will foul each other.
And check clearance around the front end, turning circle can be reduced if the tyres foul the springs or chassis.
I've no experience specifically with Chevs, but early Ford trucks were 6.00-20 and fitting 7.00 or 7.50 tyres led to all sorts of problems with gearing, braking, steering geometry and turning circle. But they were cheaper, carried a heavier load and more readily available than 6.00-20's. Sound familiar?
