I run 32 11.5 on 15x10 and have 3.55 gears and they handle them just fine and look great

 

Nice truck flareside, and Awesomeness I think your I6 will pull them just fine but it would pull much better with 3.55's or even better 4.10's

 

Im running 3.08's with 32's and it'll pull but theres hardly any power and fuel economy is about 12mpgs, still waiting on time to swap the rear end too 3.55 ls

 

I have 3.08 with the inline 6 and 5 speed, has no issues with 33x12.5. 4th gear is a good passing/pulling gear and 5th makes a good cruising gear. Keep in mind the Inline 6 is a fairly low revving engine.

 

Well I finally went and picked them up today. They were actually 15x8 inch wheels. And since I had to drive two hours to get them I only gave him 50 bucks for all four. They need powder coated pretty bad, but they aren't rusty. I'm actually happier that they are smaller. Now I can run the tires I have now.

 

My advice, with the i6 and 33's you should be running minimum 3.73. If you are going to the trouble to regear/axle swap anyways why not get the 3.73? The 4.10 would be ideal, the problem is you have to axle swap for that, if you regear with the 3.08 housing it will be too small.
