1993 VX ideling questions

[gork57]

I have Dunlop SP40s, 175/70-13. It is difficult to find 165/70-13 stock size tires, so this is the size I have gone with for quite some time now. I have the stock VX alloy wheels. Frankly the SP40s are lousy tires; one of them has developed a bulge in the sidewall, and they are vulnerable to punctures. They also show quite a bit of wear for the number of miles on them. Looks like I made a bad choice with these...

I generally keep my tires at the recommended pressure: 35psi front, 32psi rear.

I'll probably buy a set of Kumho KR21s before long. Tire Rack does have the Sumitomo HTR T4 in 165/70-13, but I'm concerned about tread wear and the fact that there are no TR survey results for this tire. On the other hand, the Kumho KR21s have great results across the board on TR's survey (#1 in category).
