Fogbelly Posted September 25, 2021 Share Posted September 25, 2021 Assuming my F350 7.3 has a axle ratio of 3.73 with the stock 34.1" tires and I change to 37" tires. This will effectively be the same as a 3.44 ratio with the stock tires. Will I notice a performance degradation with the 37s? Quote Link to comment Share on other sites More sharing options...
TraderLeric Posted September 25, 2021 Share Posted September 25, 2021 “Notice” is relative. you’re going from ~65 lb unstrung weight each corner to ~100 lbs depending on wheel/tire setup. That’s going to be the biggest difference in butt dyno feel, not the gears. I went from stock 33s to 37s on my Jeep (4.10s), and granted it’s got a lot less hp to throw at the problem, but I could absolutely tell a difference.

Hence you will not have the same UMMF or go as you would with the smaller tires. Quote Link to comment Share on other sites More sharing options...
Blackdiamond925 Posted September 26, 2021 Share Posted September 26, 2021 (edited) Coming from the Jeep world, larger tires prematurely wears suspension parts and increases the chance of a failure offroad. Sticking with standard sized tires is an easy way to cut down on costs and increase reliability. It's also hard to find larger sized tires, if you travel outside the US with your truck.

Big tires look cool though, that's for sure, plus that ground clearance. I just don't want to be in Oaxaca looking for a 37" KO2. Quote Link to comment Share on other sites More sharing options...
