Car service ramp suggestions?

I rotate every 2500 miles so the ware is very consistent between all 5 tires...theres only ever 1 with 2500 less miles then the rest. Even stretched to 5,000 i doubt there would be and issue
I did this with my old wrangler and no troubles I think I rebalanced 1 time around 30,000 and was good to go until 60,000 when traded on 4runner. Had plenty left maybe could have got many more miles out of those Duratrac

only pic I had that shows tread before trade

 

Looks worst in pic haha. Still doing 5 tire rotations forever

 

I do the 7K mile rotation . all tires are almost the same size. all tires look the same tread wear pattern. I do the X rotation . on runner...
I do this on my 2000 GM truck I get 80K miles on them and I rotate those tires 12K miles. I change the tires when the tread is 65% worn.I now have the 2nd set of tires I purchased on my 2000 GM truck.. the 2nd set has 15K miles on them .total odo miles on GM truck 175K.

tires in my area wear a bit more on the right/shoulder side. sand crap causes this wear on the right side so that is why I do the X rotation.. working great save $$$..
