The 18x8.5 will give you a tire wider than your 7.50 tire. It will give you more tread because of the width so you will have better traction as well as a slightly wider mower as the tires will add 3/4 inch to the outside of each tire. You will want to make sure you have the internal clearance for the extra width of tire without making contact with the wheel well or frame.

The Kenda K389 Hole-N-1 Bias Golf Cart Tire - 18x8.50-8 # AM40537 is a great option for your riding lawn mower wheels. They are rated to be run at 22 psi. The tire will fit wheels that are 8x7 inches which are most likely what you already have.

We have a few combination options, so you may want to consider the wheel and tire in the Kenda K500 SuperTurf Tire with 8" White Wheel # AM89992 which has a 5 on 4-1/2 inch bolt pattern or the Kenda 18x8.50-8 Bias Golf Cart Tire with 8" White Wheel # AM90002 with a 4 on 4 inch bolt pattern.

I wasn't able to track down the stock tire size for your Toro SS3225 Mower. If you can tell me what tire size is currently being used, I would be happy to verify if # AM40537 will work as a replacement or recommend a suitable alternative.

@David As long as you have clearance on the inside for an extra 3/4" then you should be just fine. Jason really answered the question best for you since you're going to be in the same situation as Dalton who asked the initial question.

Answer 1

The wheel you mentioned has a 900 lb weight rating, so the capacity will not be your problem. The wheel size is the same, but I am not entirely sure that the bolt pattern will be close enough to match up. A 4 bolt on 100mm bolt pattern would equate…

We have some 8 inch by 7 inch wheels, #AM20021, but none that are 7-1/2. You might be able to use the 8 x 7 inch wheels but you would need to determine if the tire size is compatible. Any given tire will fit a range of wheel widths so it is…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

Answer 8

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that…
