13 Inch Inner Tube Ride On Lawnmower 13x5.00-6 Straight Valve 6 Inch Rim Mower

Product Information

It is important not to mix tyre sizes or types on motorised machinery as there can be significant variation in heights and widths between different manufacturers. We have even found that sometimes tyres of exactly the same size marking can vary significantly. As with car tyres, we would suggest you replace your tyres in pairs to ensure optimum performance. If you are looking to change your tyre size, the height and width may be selected according to your needs, bu the last figure, the rim diameter, must be the same, unless you are buying new wheels too! It is becoming more common for ATV and turf tyres to be marked up in this manner. They are usually dual marked with their traditional inch dimensions, but if you are handy with a calculator, it's possible to convert from one to the other. For example, a 255/60-10 ATV tyre would be 255mm wide, have a 153mm sidewall height and fit a 10" rim. Converting these dimensions to inches would give us 10" width, 6" sidewall height and 22" (10" rim plus two lots of 6" high sidewalls) overall height. In traditional ATV tyre size marking, this would become a 22x10.00-10. As already mentioned, it is important not to mix tyre sizes or types on motorised machinery as there can be significant variation in heights and widths between different manufacturers. We have even found that sometimes tyres of exactly the same size marking can vary significantly. As with car tyres, we would suggest you replace your tyres in pairs to ensure optimum performance.

This method is widely used on turf and ATV tyres and is probably the easiest to understand. The first part is the overall height (from the ground to the top of the tyre) of the tyre in inches, the second part is the width of the tyre in inches, and the third part is the rim diameter in inches. This method is becoming obsolete, but you may still have tyres marked in this way. Measurements can be in inches or millimetres (look at the examples above, it's fairly obvious which is which). The first part is the overall tyre height, the second is the tyre width. There are several methods for giving the size of tyres, with measurements sometimes in inches, sometimes in millimetres, sometim es in both! To help you understand a little better, we have examples and explanations of each method below, from which you should hopefully be able to recognise your own size markings.

A 195/50R13 tyre would be 195mm wide, have a sidewall height of 98mm, and fit a 13" rim. The approximate overall height of the tyre can be worked out by converting both dimensions to either mm or inches, and adding the rim diameter to twice the sidewall height.

We understand that it isn't just great service that you need as a customer, but value for money too. The load index and speed index is gradually replacing the PR marking for tyres. The load index is given by a number between zero and 159 in our chart, but can be much higher. The speed index is given by a letter (or letter and number in the case of 'A' speed rating) between A and Z. Typical examples for our type of tyres would be 68M, 55N or 38F. Any ATV tyres we list with this marking will also be 'E' marked and fully road legal. Contrary to the PR marking, the LI and SI give unambiguous and comparable information on the load capacity which can be drawn from the tables below; Speed symbol The rim diameter is not mentioned in this size marking, but it can be easily worked out, because the tyre sidewall height will be the same as the tyre width. So, an 18x4 tyre is 18" tall, 4" wide, and fits a 10" diameter rim (18" overall height minus two lots of 4" high sidewalls). The modern equivalent size for an 18x4 would therefore be 4.00-10. This is the traditional method for marking car and van tyres, so is also used quite often for trailer and caravan tyres. The first part is the width of the tyre in mm, the second part, if present, is the height of the sidewall expressed as a percentage of the width, and the third part is the rim diameter in inches. If there is no percentage indication in the tyre size, the tyre sidewall height is taken to be 80% of the width. You may sometimes see a tyre with the 80% in the size eg. 155/80-13. The 'R'. when present within the size, means the tyre is of radial construction.Originally, tyres were marked with the exact number of canvas layers (plies) built into the tyre. This was an indication of the strength of that particular size of tyre. It's fairly obvious that a 4 ply wheelbarrow tyre will have a different load capacity to a 4 ply car tyre. As stronger materials were developed, the number of layers could be reduced whilst still maintaining the same strength in the tyre. The designation Ply Rating therefore does not indicate the actual number of layers or plies in the tyre, but the number of layers originally required to give the desired load capacity. When working with PR marked tyres, you must use the actual manufacturer's data to determine the load capacity in kg. This value can often be found on the side of the tyre adjacent to the ply rating indication.
