My local track has really poor dirt this time of year. It is like concrete with marbles on top and a little duff in some corners, really hard on tires. It sucks but I still like to ride it one or two days a week so that Im in decent shape when I get a chance to ride a good track.

I have another set of wheels that I want to throw some of the cheap tusk brand hardpack tires so I can ride this track and not feel like Im wasting so much money.

My question, since this is a 2.15 rim, do I stretch the 100x90/19 or do I just run the 110x90/19? They dont make a 110x80/19 in this tire.

I put a 100 Pirelli on a 2.15 rim not that long ago for a guy. Went on fine. 110 90 would be fine too

100 will go on a 2.15" rim no prob. That is how the KTM/Husky 125's come stock. But I'd think you'd want the 110/90 for the hardpack with marbles.

Haven't got all the parts yet to run these on my 250f so I threw them on the 125. It was great, noticed the extra weight made the rear want to basketball a bit, but added click of rebound made it perfect.

110/90-19 all day long. Hard pack needs a big tire and low pressures.
The only time I'd run a 100 tire on a 250F is maybe in the sand where I want it to rev/spin.
