I just ordered a 2.5 in front level that allows clearance for 35 tires. I plan on purchasing 35x12.50s and putting them on my stock 17 in rims that are 7.5 wide. now all the pros tell me I need a 8.5 wide rim but ive been told by several friends and have read on here as long as I run a lower psi it will have no issues. I also purchased 1.5 in wheel spacers. thoughts?

I have thoughts and opinions based on experience, but you're probably not going to like them.......
1) 35/12.50's are going to rub some with just a 2.5" level. Not terrible, but some.
2) It's going to be a lot worse with spacers.
3) Adding spacers, especially with heavy wheel assemblies, has a bad track record of shearing studs and throwing wheels.
4) A 7.5" wheel is going to shorten tire life somewhat. The tread centers will wear prematurely. Lower pressures will help a little.

Thats extremely far fetched, he's putting them on stock rims so it won't be heavy. Also if you torque every bolt and lug nut to proper specs you have no worry of anything happening. I've never heard of spacers falling off or any problems when everything is torqued properly. It won't shorten tire life if he runs a lower psi.. it will wear evenly
I've not just HEARD of spacer failures, I towed several of them in when I drove for AAA. In addition to the risk of a wheel departure, spacers are hard on wheel bearings and ball joints. It's a simple geometry/leverage issue and can't be avoided.
The narrow rim is tolerable, yes. Lowering air pressure enough to get a good chalk line test is probably going to put him down in the mid 30's up front and the low 30's in the rear, so load capacity is going to be greatly reduced (if that's a concern), handling will be somewhat spongy and fuel economy will suffer. Yes it will wear evenly, but you're going to be paying for it elsewhere. Extremely far fetched? I don't think so. I stand by everything I've said.

I guess that was a little confusing. I said wheel assemblies by which I meant tire and wheel. The tire is what is heavy. There is very little difference (relatively speaking) in the weights of various rims.
