Tires Will NH 1620 turf tires fit on TC25D?

computerboy · Nov 2, 2004

I have a TC25D with R4s and have been looking for a set of turf tires. I have found an individual that has Firestone R3 tires and wheels for sale that are on a NH 1620. The specs are 13.6 - 16 rear and <font color="red">25</font>-8.50-14 front. The specs for the R3 turfs for the TC25 are similar (13.6 - 16 rear and <font color="blue">24</font> -8.50-14 front). The fronts are different in the first number.

My question is will these turf tires fit on my TC25D? Also, what should I look for when looking at used tires?

Thanks,
Mike

Get the specs for the turf tires for the TC25D and then see if they match up with the used ones. Buying used other than the specs will get you into trouble. The backs have to match up with the fronts or you will get the backs and the fronts fighting each other and will do drive train damage. Just be cautious. The money saved for used could end up costing you more than the new ones right up front.

Murph,

I listed the specs for the used turf tires and then what my old brochure for the TC25D has for specs above. The only difference is the first number on the front tires is 25 for the used set and 24 in the brochure. I am sorry if my post did not make that clear.

I guess what I want to know is if the numbers on the used set of turf tires is wrong and it should be 24 (not 25) and if the bolt pattern for the turfs on a 1620 is the same TC25D. I have called my dealer but he was not sure and needed to do a little research. I thought someone might know. The guy is going to send me pictures and double check the tire specs for the front.

Thanks,
Mike

Mike,

I guess I did not catch that. You may want to find out or someone here will chim in I am sure as to what the difference is. The width of the tire is not so important when matching as much as the height.

Not gonna fit. To clarify, the bolt pattern on the rims is different so the rims are of no use to you. And the front tires you found will be ever so slightly larger in diameter, circumference and loaded radius, however you choose to measure. This will increase the lead ratio, causing extra scuffing in 4WD and hard shifting out of 4WD.
