19.5 tires/wheels

[Cattletrkr]

What sort of mileage can I get out of these? 100K+

Can I expect to see over 100K on a set? Yes

I'm wondering if it's worth it to upgrade, YES!!!

or if I should just get new tires and be done (for another 2. 5 years). NO!

My absurdly expensive Mich 19. 5's have already paid for themselves and half the rims. One more set of tires and I'm money ahead. If you don't plan on keeping your truck to 200K then the 19. 5's probaly won't save you much because the rims are soooo high priced.
