    Yup - if I get a minute that’s how I dialed mine in after changing gear ratios.

    It’ll take a bit of study, and run down the road and adjust - but it is spot on.

    I’ve never had trouble finding lp 24.5’s. I hate the way lp 22.5’s look. I run tall 24.5’s on all but one truck and it’s got lp 24.5’s. I run tall rubber on my sow belly hoppers and cow pots for clearance.

    I “used” to think the same way, Only tall rubber for me. Tall rubber was very popular, every tire shop had them. The core “were” valuable, now, today, it’s the complete opposite, tall rubber is not very popular and they look funky :D. But I understand, it depends on your application on what you do. Current truck have LP 22.5’s.

    Yes, sorry - I missed that. Bad reading - I should know that after owning one.
