I'm having a really hard time finding tires for my tractor.

I have a 2000 John Deere 4100 4x4. The rear tires are 315/75/D15 or 12.4x9.3 x15

I have worn out turf tires and would like to get some Ag (R1, etc) tread tires.


Thanks and great forum!

On a 4100, The standard R1's were 9.5-16 in back, and 5-12 in front.

Turf, R3's were 315x75D-15 rear, and 23x8.5x12 in front.

R1's called for a different 16" rim on the rear as opposed to your 15"

Can't say if the R1 fronts will also fit your rims.:confused:

Do you know of a R1 that will fit my wheel?

I would suggest checking with either a John Deere dealer, or better yet a commercial tire dealer that handles AG equipment.

Or search eBay for a set of rims with or without tires.

To go from Turf's to R1's you will need new rim's...the ones you have will be to wide.

Anyone know how wide the rear wheels are on a 4100 with turf tires?

Did those work? I’m looking to do the same thing. I thought the backs were 33x12.50x15. From what I’ve Gathered online you have to keep the tires close to what came on it or the same ratio for gearing/rotation of front to rear tires. Any Insight would be greatly appreciated. I’m having a hard time finding 16” rims or a pair of 15” r4 or r1 for the back to replace the useless r3 turf tires. Thanks

You have a greater issue than just will fit for the sake of not damaging your tractor. Since the rear tires are typically and reported sizes support this much larger than the fronts, rolling circumference comes into play. JD has done all this math for you by providing tire sizes in given tire types.
My suggestion to avoid buy different wheels, is look for the turf sizes in industrial tires (R4’s). While a different tread, they are more similarly sized to turfs than R1’s.
