webley455 Posted March 18, 2019 Share Posted March 18, 2019 I need replacement tyres on my Fox, it currently has the original Dunlop Runflats which are starting to crack. I have been offered some new 12x20 bargrips. can these be fitted to the Fox instead of the 11x20’s or are they likely to cause damage to the vehicles running gear?

Here is the parts book page with the list of bits for the wheel though sadly there is not an illustration. It shows what could be two types ? And states that it is a "Dunlop HB133 modified". I don't know what the modified refers to maybe someone way more qualified than me could comment. It does show that the wheel is fitted with standard 11-00 x 20 Michelin XL tyres with a "Flap, rust , slip". Considering that these vehicles could motor along on roads at reasonable speeds, not just potter around a yard, I would say the fox would be OK. I hope that helps a bit.

0 Terra1936 Posted December 11, 2019 Share Posted December 11, 2019 This is very informative. Locating these tires in the states in usable condition has been a challenge. I wanted to have all info before I begin my purchase journey. Thanks again! Quote Link to comment Share on other sites More sharing options...
0 john1950 Posted December 11, 2019 Share Posted December 11, 2019 Going from 1100x20 to 1200x20 you will need to check all clearances including full lock, depending on tyre brand and tread pattern. Going from memory there will be roughly 4 inches difference in tyre diamiter and a similar width difference. For a given engine revs speed will change also engine work and gearbox driveline peramiters will change. Engine overheating could become an issue. Brakes will have to work harder because of the larger tyres. Quote Link to comment Share on other sites More sharing options...

They are out there, maybe not next door though. Iain Quote Link to comment Share on other sites More sharing options...
0 Terra1936 Posted December 11, 2019 Share Posted December 11, 2019 I have located some of the same sizes G177 The difference is my current is just X and the new is XL? Not really sure the difference. I have purchased from Boyce before. These are from Canada they are XZL 's? https://www.ebay.com/itm/Set-of-5-Michelin-XZL-11-00R20-off-road-tires-/181182206801 Quote Link to comment Share on other sites More sharing options...
0 Mk3iain Posted December 12, 2019 Share Posted December 12, 2019 If you can get XL at a reasonable price, OK, but if you are not too bothered about being totally original then XZL. They are a very good tyre (tire). Quote Link to comment Share on other sites More sharing options...
0 Terra1936 Posted December 13, 2019 Share Posted December 13, 2019 Do you know the difference between X XL and XZL ? I have located both XL and XZL pretty close in price. My originals are X. Quote Link to comment Share on other sites More sharing options...
0 Mk3iain Posted December 13, 2019 Share Posted December 13, 2019 Only in my experience,. I'm not an expert, others on here are far more qualified. As far as I am aware the XZL have in effect replaced XL in military use, I suppose if the Fox was still in service it would be fitted with XZL. The XL is probably more biased to off road and seems to wear faster on Tarmac but is a good all round tyre. If it were me and not intending to do big miles I would stick to XL. They are correct for the vehicle and look right. If it's down to driving a lot and road performance then the more modern XZL. In a perfect world a set of XL for show and XZL for driving around. Just like having winter tyres for your car, a tad more expensive though. Iain 1 Quote Link to comment Share on other sites More sharing options...
0 john1950 Posted December 13, 2019 Share Posted December 13, 2019 Michelins X tyre range are a long evolution tyre designed and developed over many years. Original X tyres are classed as vintage type with a side wall and tread base designed to perform different tasks within one carcase. Letters after X signify modern stage development through its lifetime, different compounds and tread patterns. That is my understanding of the range. 1 Quote Link to comment Share on other sites More sharing options...
