71_Bronco 1,072 #1 Posted August 24, 2020 Got some new front wheels / tires for my Lawn Ranger, as well as a brand new set of spindles from Lincoln at A-Z Tractors (still can't believe he had a set). Front tires are 4.10-6 Carlisle Stud tires, mounted on 6" diameter x 3" wide wheels. I went with 2-piece wheels for ease of install, and obviously went with a Carlisle tube. Front tires are 2 ply and say max inflation of 24 PSI. I can't find a max PSI rating on the tubes. Anyways, I filled them up to about 20 PSI to seat the beads and get them all situated. Once they were on, I put them down to 10 PSI as a starting point (my Commando 8 manual says 12 PSI front tires for reference). When at 10 PSI, I can squeeze the tires and are able to actually squish them without straining my hands. Does anybody know what I should set these at? I'm thinking maybe try 15 PSI? 20 PSI seemed a little too firm, but that was just handing the wheels / tires on their own. Share this post Link to post Share on other sites
Lee1977 7,049 #2 Posted August 25, 2020 I push down on them with my hand fi they will give just a little I call them good. Most tire gages don't regusture acuracly with that low a pressure. I never use one on my Wheel Horses. 1 Share this post Link to post Share on other sites
cleat 7,055 #3 Posted August 25, 2020 I have a low pressure tire gauge that only reads up to 20 PSI to use on lawn tractor tires. Share this post Link to post Share on other sites

953 nut 58,124 #5 Posted August 25, 2020 As lite as a Lawn Ranger is and as small as those tires are if you run much over 12 PSI they might as well be solid tires. Share this post Link to post Share on other sites
Pullstart 64,729 #6 Posted August 25, 2020 Just remember, the tires are literally your only means of suspension for the tractor. Squishy tires is an easy lift on the goods Share this post Link to post Share on other sites
71_Bronco 1,072 #7 Posted August 25, 2020 I just looked up the manual for the 33R (one year newer than my 32R), as that version came with pneumatic tires. That tractor has 3.50/4.10-4" tires, and the spec in the manual is 20 PSI. Mine are a little bigger, with the 6" wheel, but the width & sidewall height are the same.
