Tyre sizes and what they mean borrowed from another site....

185 65 H R 13

185 :-

This is the width in mm of the tyre from sidewall to sidewall when it's unstressed and you're looking at it head on (or top-down). This is known as the section width.

65 :-

This is the ratio of the height of the tyre sidewall, (section height), expressed as a percentage of the width. It is known as the aspect ratio. In this case, 65% of 185mm is 120.25mm - the section height.

H :-

This is the speed rating of the tyre.

R :-

This tells you that the tyre is a radial construction.

13 :-

This is the diameter in inches of the rim of the wheel that the tyre has been designed to fit on.

 

185 65 R 13 91 V

185 :- Section width

65 :- Aspect ratio

R :- Radial

13 :- Rim diameter

91 :- load rating

The bigest size that I could get on my 1998 vitara was 215x75x15 and with that I had to take the front mud flaps off as they rubbed on full lock to go any larger than that you ether need to lift the body or have longer springs.

 

are you shore that they are 80s as I would have thought that was a bit big but in answer to your question I think you can get 235x75x15s on but they will rub so they are not recomened without a 2" body lift this will give you some idea of sizes.
