Hi need some advice/help with tyre sizes
At the moment my tractor was fitted with 13.6 / 12-38 my rim measures 12” wide and 11” where the wall sits (if you understand) see pictures.
My question is can I put a wider tyre on the rims I have ?

Thanks Tim

Hi Tim.
You could fit a 14.9 x 38 tyre, but that won't give you much more width, and if I remember correctly they are expensive.
The other sizes of tyre with appropriate the same R/C would be 16.9/14-34. or 18.4/15-30. which would require new rims and centres.
