2002 S10 extended cab (PRO ET) with complete Calvert rear suspension, Moser M9 with 4.11 and spool.
After 240 runs the 275Pro DR are now replaced with 28x10.5x15 PBR.

The drivers side 275 had surprisingly more wear than the passenger side.
Tires are at 20# air and the Caltracs are 1/2 turn tight, shocks full loose.
Trans brake 3300rpm 2step, low HP LS 6.0L, TH400 running 11.50 117

Weights with driver 3452
DF 1057, PF 964
DR 791, PR 639

Weight with out driver 3238
DF 950, PF 942
DR 694, PR 651

Any thoughts why the drivers side has more wear with a spool?

Tires never moved on the rim.
Truck leaves and drives perfectly, dead hooking all the time.

Debating on adjusting the bars to even the weight while on the scales and adding/moving some weight.
Just surprised with the different wear with a spool.
