Kubota B7500 HST
I need a front tire (or tires). 21x8.00x10 Turf and Field ... Kubota discontinued the part number.... BS!!

Firestone discontinued tire, a company bought a bunch and are gouging people on Ebay at $152 a tire!! BS again!

So, I need a replacement or what's size can I use on my 4 wheel drive that don't screw up the ratio/sync...

If I have to get two new tires/rims R1 will be my 1st choice or something more aggressive than turf.....

HELP!!! 606-831-1266 theboman@theboman.biz

Can you measure the tire itself? The reason I ask is that actual sizes vary by tire brand and model. One models 21x8.00x10 might be the same size as another models 22x8.00x10.

To pay $150 on Ebay and be all done seems logical to me. Otherwise, Id try BKT.

There are a couple of different older threads on this subject...I went the through the same issues a couple of years ago...
...it is all about "rolling circumferences"...

The reason I asked is that Carlsile (and other manufacturers) have several turfs (or turf-ish tires) that are 20x8x10 or 22x8x10 but they vary in height depending on what model you look at and with a diameter or circumference from the tire you have now, I could probbaly point you to a match.

Specifically, the Carlsile All Trail 20X10.00-10NHS (pn: 5100454, available for $75 on Amazon) is supposed to have a mounted diameter of 20.13" and a mounted width of 8.8" with a weight rating of 695# per tire
The original tires (per: B1700 Front tires? - OrangeTractorTalks - Everything Kubota ) had a mounted diameter of 20.5.
That should give you a rolling circumference of 63.27" vs the stock rolling circumference of 64.43"
With new tires that would be a problem, but being as your back tires should be worn, the ratios should be close enough to work.

on the Ebay tires.... If I'm gonna have to pay $150 for one tire, I just as well pay $200 or somewhat higher for a more aggressive tread type on two tires..... The $150 tire is PRICE GOUGING and those type businesses should be boycotted!!! I've been a Kubota fan since day 1, for the past 12 years... now a days..... I can't say they'd be my next choice of tractor....too many time they have did things like this.... POOR CUSTOMER SERVICE!!!

I gotta back it out, no other choice where it sits... Hard to steer with split brakes on a hydro too :)
As far as that tire, I won't waste my money on a two ply that'll be too wimpy.
Just as I posted that I realized my rim sizes were different... Just all flustered on my situation at hand.
I do appreciate all the advice, pointers, help from my "tractor buddies" here on TBN!!

I just found a 21 x 11 x 10 in Carisle...

A ratchet strap to hold the blown side up in the air should let you steer if you use the bucket to stabilize it. Otherwise, a string or light rope tied to the forward pedal would let you back out while using the split brakes.

Just check the mounted diameter of them to make sure it will give you rolling circumference that is close to stock.

You need to be careful that they remain matched to the rears. Im assuming you have a 4WD?

Yep I'm aware of that and mentioned that.. Kubota said I can use 22 x 8 x 12 but if I gotta buy TWO TIRES AND RIMS because of their BSing ways at Kubota (and yes it is their fault!) I want to go with a R1 or similar.
