I liked the 15" wheels on my T100.
It made it easy to get Michelin LTX M/S LT tires.
I think they were 31x10.5x15 - and I got over 80k out of them.
I happen to have 3 new take-off 15" T100 steel wheels available...


My Tundra has 16" wheels and finding good truck tires took time and money.
I ended up with E rated tires on the Tundra.
