wd45 tire size

I know this has probably been answered many times before but never paid attention until now. Looking at buying new tires for my wd45. Tractor is used very little since I live in town and only use it to pull a spreader several times a year. Also may be used in a parade.

11.2 x 28 are going to be way too small for a WD45. that tractor is supposed to have 14.9-28 tires on it.

I put 14.9 x 28s on both my wd45s. that is the size they came with. the wds had 13.6x28 tires. 11.2s are way to small.

I put 14.9s on my 45 and they work well, look good. I've got 13.6 on the WC and also on the WD. These sizes could be ordered from the dealer on your new tractor, but I believe they are all one size over "stock". I've put 16.9 on both D-17's and they look good too. Saw a WD-45 with 16.9 at a pull, it looked a little silly and he ran short on power real fast!

ours has had 16.9s on it for years. has a nice stance with 6.5x16 up front. power has never been an issue either.

The width of your rims have a factor in this. 13.6 tires work well on 12" rims. they also look good on the 45. 14.9 would be an improvement to the wd-45. Check the width of the rim, then check see what your options are. Gd luck!

contrary to many above, the WD45 came new with 12- 28 old size, now 13.6 x 28 From the factory. It did NOT come out with 14.9 x 28 as we call them now. The old 14 x 28 is not the same as the 14.9 -28 we have now. Those would be more like the 16.9 x 28 like we currently are familiar with. A current 13.6x 28 is the closest thing to stock you can get now. Yes, 14.9's look pretty good, but they also will get into the fender if set in all the way and things go slightly wrong, just as many 45's will show a crinkled hind end on the fenders. The WD callled for 11-28 originals now 12.4x 28.

The WD callled for 11-28 originals now 12.4x 28. Early 45's (like 1953's) might have had 12 in rims and 12-28's, now called 13.6-28. Later WD-45's had 13 inch rims from factory and 13-28's, now called 14.9-28. Nebraska test shows 14.9x28 as standard. AC operators manual shows 13.6x28 as standard and 14.9x28 as option. Almost all I have ever seen had 14.9x28

Going by the A-C manuals, they would be 13.6 x 28 at least till 56. I have my grandfathers 56 with the manual he got with it bought here in Illinois, with the original 12 x 28 (old size) tires still on it. I am pretty sure the largers were an option, but NOT standard.

I think it's time for a group hug. 

Ok, I know this thread is ancient but it prevents me from re hashing a lot of info. I just bought a WD45 single front wheel and it has 13.6 by 28 on the back. They are usable but will replaced once I completely overhaul the tractor. Can 14.9 by 28 tires be put on the rims I have for a 13.6 by 28 or is it too big?

Thanks! have always liked a bigger tire and figured if I'm gonna restore this tractor completely I'm gonna do it my way.

I have original owners manual in my hand for 1954WD45 and have the tractor too. Manual lists 11x28 and 12x28 for rear tires.  And optional 9x38.... Didn"t know that. LOL. Having said that I now have 14.9x28 Firestones on it. Good size but as someone said you cannot bring the wheels all the way in. Mine are on 13" rims. Originals were 12". They were corroded pretty good from calcium.

The one I bought is a 1956 model with a single front wheel. It has 13.6 by 28 but only one of the spin out rims is on the tractor. I found the other in the weeds beside the tractor.
