Tires Pirelli or Falken

I used the 615k+ last summer they were great for multi purpose use. I did a few track days (6) and daily drove them all summer. Warm up is almost instant, they do fine in the wet. I'll be purchasing another set when track days pick up again.

I recently switched from LT Toyo at3s to "SL" Falken at4ws. IMO the xterra is not heavy enough for the LT tires, it rides and drives so much better with the lighter sidewalls of the falkens, as well as feeling more responsive from less rotating mass.

I have the LT version in that exact size. They are surprisingly great on bitumen with hardly any road noise which is great for your use case. Currently at 35k and no noticeable wear at all with mostly bitumen use. They seem like new.

I was in the same boat as the OP, and went with RT660s.

660 is good bang for the buck. Not as fast as the top tier tires but two or three times the lifespan.

I went with fallen 615+ not the fastest but should last a good number of runs

I'm in a similar boat as you I did the 615k's last season. Personally I am overly pleased with these tires they have been everything I've wanted them to be. And I'll probably get another set of them this year.

My RT615K lasted like 8000 miles on a Honda Fit with 50:50 miles.

Pirelli's are junk, id switch to some Michelins.

Mine came from Berlin with PZeros (my M3LR had Pilot sports 4S´es) liked the michelin much more, Pzero is a garbage tire.

But it is decent, not a lot of roadnoise, so that is key.
