So I have been looking for a set of rear tires for my 1972 MTD Wizard. The rear tires that are on it now are sears tires 23x9.50-12's I know the manual calls for 23x8.50-12's. I came upon a new set of 22x7.50-12's Carlisle turf treads for a good price and was wondering if they would be ok on the wizard. I held one up to the sears tires on it now and did some measuring and they look real close. I do need a bit of clearance for the 3pt hitch. I get lost on these tire sizes! Please explain!!!
Tire Size Explanation?

1st # is the outside diameter
2nd # is the width of the tire
3rd # is the rim diameter

so in other words, there is little difference to make any difference? I do need narrower tires, but its the first number that concerns me.

The 22x7.50-12 will make the tractor sit 1/2" lower and have a 1" narrower tread width than the 23x8.50-12.
The same tire size made by different tire company's can have different measurements when you put them side by side.

The 22 dimension wouldn't be awful but the 7.50 width would be too narrow for my taste, esp. if your goal is to spread out the weight which I assume is the case because you're talking turfs.
I've seen 23/8.50x12s and 23/9.50x12s turfs for $50. Unless the 7.50s are much less money, to me at least, that's cheap enough to just run the right size.

Here is a quick tire rundown as it concerns GTs.
going from a 23x9.50-12 to a 22x7.50-12 will make a lot of difference to you as far as traction, speed, and clearance. those tires on your rims should work as those were the combos being used, however, your clearance around the tire will increase, but your overall ground speed will decrease. your traction will change also as you will lower your footprint size on the ground. on a tractor such as my Springfields this makes very little difference, but on your tractor you will wonder what the heck you were thinking when you decrease tire size. Next, you are mixing your tire brands and as Doug pointed out you don't know how the manufacturer measures them up, some run truer than others to actual. If I were you I would not mount a smaller tire, as those 22x7.50-12's are only 2 ply sidewall, so you really need to seek a tire with a 4 ply, especially since you mentioned a 3-pt hitch, and those implements can get hefty on a 2-ply tire.

ok, now that im convinced not to put these tires on, where is everyone getting their tires from, for a reasonable price???

You can blast a 22 7.50 12 on the rims for the reason that you would think for a 23 10.50 12 tire there would be a 10.50x12 rim well the rims are commonly 7.5x12 john deere runs 8.5x12 rims most pullers run rims the same width as the tire so the tread stays flat (for traction) likely your rims are 7x12 so there would be 1/4 bulge on each side of the tire

here is a explanation of how you know big they are.
23 is how tall the tire is if you measured from where it is setting on the ground to the top of the tire so it would be 23 inches tall
10.50 is how wide the tire is. So the tire would be 10 1/2 inches wide
12 is the rim size, so the tire would fit any 12 inch rim
Hope this helps. ~Jake

GCT wholesale at www.greatercleavelandtire.com has good prices on Deestones and you will get in two days most times. They also have Kendra, but not familiar with that brand from China. Deestones are imports from Thailand, not sure if any better. I've gotten them often and like them. BUT, I never keep stuff around long and can't tell how well they last!

I've made two purchases from Tires-Easy recently. Both went smoothly. First was snow tires for my wife's Xterra and I just got a pair of front tires for my PA Meteor last week. They seem to have a huge selection of lawn and garden tires. I know the name is cheesy but when I did a little homework on them I found out the parent company is Europe's largest online tire dealer, kind of the Tire Rack of Europe. They have great prices and they accept Paypal as payment. The order processing and shipping was a bit slower than Tire Rack but then it was the week before Christmas....
Just enter your size in their search page. As I mentioned, they have 23x8.50/12 turfs for $50 +shipping. The 15x6.0/6 fronts that I got were only $15 something each.
