??? Tire scape on rear - even after new shocks ???

[Jamler3]

Got new wheels and tires... Didn't have any issues until about a month ago.
Was cruising down the Garden State when I hit a dip in the road on got some tire scrape... Tire size is 255/50/17 which actually has only 3/10's of an inch less sidewall than stock... Does extend slightly past well in rear, but I've seen folks with 275's on the back so that shouldn't be a prob.

Thought it was the shocks........

Went to Brooklyn to visit Eric, we put on a new set of Sensa-Tracks...
Definitely smoothed the ride but hit a couple stiff dips on the Belt Pkwy
and got scrape... Was kinda pissed but now concerned.

Air springs look like they are in great shape (Car is garage kept - Year round)
Pump up when started and all... HOWEVER, do not get as much air as front.

When I start it up, the front pumps first, getting ~ 10-12 seconds of air.
The rear then kicks in, BUT only gets ~ 6-7 seconds of pump.

Is it possible that the rear is just not getting enough air...? I don't think anything has changed in terms of the sensor settings... Haven't had time to check to see if the sensor is at its lowest point, which I believe in turn makes the Air Spring pump to its fullest.

Is it possible the system is lacking air???? Can I just pump some more in there? Whatcha think??????????????

Front will always need and want more air.

275's will usually rub if you have 17x9 with a 36mm offset. Mine did, I did a fender roll with a tool that bolts to the hub and no more rubbing. Just do a search on the net for "fender rolling tool" and there are a few places that will rent them out, I got mine from a place called SLP or SPL (can't remember) performance. I paid for the whole thing ($130 or so), they shipped it, then when I was done I shipped it back and they refunded me like $110 or something.

I've got 255/50's all the way around...
Can you post a pick of yours with the "Fender Roll"... Not sure I want
to do a bod mod. I'd rather just stiffen the springs...
