In this episode I fit the car with new 18" wheels and tires. The wheels are from Summit Racing, they're Vision Wheel P/N 143-8961GMML12, 18"x9.5" wide with a 5.75" backspacing. The tires I used are size 275/40 ZR18 front and rear. The fronts are new Nitto NT 555 G2, rears are used Goodyear Eagle F1 GS. You'll get to see some of the latest reverse tire mounting and road force balancing technology too.
I also tackle a charging system gremlin that I thought I fixed in Episode 1. The final result with the new rims & tires are shown at the end along with close-ups of the clearance.
Here is a link to an excellent video that I watched at least a half dozen times before purchasing my rims. Caution, it does have a few F-bombs in it, but his content and information is spot on. He shows how to fit the absolute largest tires possible on an A-body Chevelle with stock wheelwells.
