Hi Darren, yes the General Grabber has changed pattern style due to new European laws regarding off road tyres and whilst it doesnt look as good as the old style, it still got rated very highly in the Land Rover magazines. Doesnt appear BF Goodrich do the all terrain in that size but it might pay to ring the usual suspects - John Craddock, Paddocks and Silverline.

 

Good luck,

Derek

That is a funny old size...! Cooper STT is close, may or may not fit, will be a bit bigger than what you're running... closest is LT275/65R18, 50mm taller/25mm larger radius and 20mm wider/10mm each way than existing 255/60R18... all things being equal [discounting additional tread protrusion and apart from the fact that it might foul bodywork etc,] you will lose just under 3 degrees from your maximum steering angle in fitting this larger size. Good tyre though....

55 is just a slightly lower profile, basically 55% of the width rather than 60%...

 

here is a useful bit of 'rithmetic for you...

 

255 - width of tyre in mm = 255mm

55 - aspect ratio, or height of sidewall as percentage of width, 55% of 255 = 140.25mm

18 - Wheel diameter in inches, or in mm it's times 25.4 = 457.2

 

Add that lot together, 457.2mm + 140.25mm [x2 for top and bottom of tyre] gives you a diameter of 737.7 diameter [doesn't allow for variations in tread depth & projection, all tyres are different]

A 255/60R18 has a sidewall height of 153mm, so 13mm taller than a 55 profile near as makes no difference... That's not a lot but bear in mind you're losing that space beneath your diffs...
