That means I won’t need to get new front tires...anyone know if I still have to move the wiring harness on the 315/30’s? I like not having to trash my existing front tires.

You you will need to move the harness...it's super easy. Also take a plastic panel fastener secure the liner where the harness was. There is a hole in the frame right there, so poke a hole in the liner and install the plastic fastener. It will give you more clearance so you don't rub a hole in the liner.

When I first got my wheels I started off with 555G2's front and rear. 305/35 Rear and 275/35 Front and it gave that Stablitrac a FIT. I had to replace the rears to 305/30 to resolve that issue. Rear 555G2's are 28.41 Diameter so if the Drag Radial is 28.58. I may likely run right back into that nightmare.  |
You might...the thing with these ECM's is you program actual measured tire height in inches. You also go off of installed height with the tire installed on the car not manufacturer specs. So even though the 555r specs 28.58 it actually measures around 27.7 on the car. Just like the factory 275 run flat specs 27.6 but measures 26.83 loaded. So that is the number you use to calibrate speedo and shift points.
Point being different tires may squat more or less depending once installed on the vehicle. I would measure both the front and rear while on the car to see actual difference. Off the top of my head I think you will need a different tire up front or get a R888r in a size that works.
