if the tires are a larger diameter than stock, you have changed your overall gear ratio. this reduces your engines rpm below the stock levels. its as if you are in overdrive in all gears. this means your engine is lugging in low gear.
you can go to randy's ring %26amp; pinion and use their rpm calculator to compute engine rpm stock vs new tires. you can also use it to compare differential gear ratios to correct this.

we had the same problem with our 85k10. it came with 373 gears when we added 33" tires performance really suffered, changing to 411 gears corrected thisWhy wont my truck spin the 22 inch wheels and tires.?

A set of lower gears would definitely help. I am assuming you have 3.55's. If you are really concerned with boiling the goodyears, swap out your rear ends for a set of 4.11's or 4.56's but be warned that your fuel economy is going to suffer big timeWhy wont my truck spin the 22 inch wheels and tires.?
Your gear ratios are made for pulling and hauling, not burning rubber.
Also, why the fxck did you put 22 inch rims on there? Sidewall gives many performance advantages, low profile tires are bad!
1. The wheels are too big AND
2. Your rear axle gears are geared low for the purpose of fuel efficiency. If you had higher ratio axle gears that would give you added torque for a better launch.Why wont my truck spin the 22 inch wheels and tires.?
Those are some BIG wheels to be turning. You probably have a high gear ratio also and an automatic transmission doesnt help any either.
Geared to high or low in the rear end.
Your tranny hates you.
does it have traction control?
