bedford Posted August 18, 2014 Share Posted August 18, 2014 Have a set of NOS 12 x 20 bar grip tyres,been on for a couple of years,sidewall now showing signs of cracks. Not too deep but short surface cracks,anyone know if this would be an MOT failure. or does anyone know if it is possible to find new bar grip tyres,not new old stock. Thanks.

Sean N Posted August 18, 2014 Share Posted August 18, 2014 IRRC it depends on the extent and depth of the cracks. You can look up the MoT tester's guidance online - it's on the VOSA site and elsewhere. The cracks have to be below a certain size, I can't remember what, and you mustn't be able to see the construction of the tyre at the bottom of them.

RattlesnakeBob Posted August 19, 2014 Share Posted August 19, 2014 Choose your MOT station with care ....I'm not advocating you drive an unsafe vehicle but ...dependent on where you go there are some real jobsworths in MOT stations that just love to fail vehicles ...especially older ones......... I once had a Series One with the original steering box on ( in good condition though and adjusted correctly) ..now....anyone that knows such steering boxs probably knows that MOT stations used to be issued guidelines over how much play should be expected in them ?.....mine was well within this amount of slack but still ....by modern appearances and standards .....sloppy as anything.........No way said the man.....I argue and bicker but still "no way!" was the answer...."Dangerous that is mate !!...more than my jobs worth!!!" etc etc ...... consulted a local mate who'd worked on LRs since the mid 1950s and ......he directs me to the MOT Garage he uses where the older fella there is well versed in Landrovers and their intricacies.... ...and? ......"No problems" says the man....."here's your new ticket!" So ...I guess the answer is?... ..search a MOT Garage with someone that can 'see the sense' rather than just 'read the rules'.... Quote Link to comment Share on other sites More sharing options...
bedford Posted August 19, 2014 Author Share Posted August 19, 2014 Thanks for the info.a tricky one this as the Tyres are new old stock. And as the truck has to have a hgv test,I am most likely to see the same vosa tester,as in our area we now have to use authorised testing facilities. The 12x20 are a big heavy tubed tyre and look like only age cracks on the outside not on the inner,if I did manage to get some replacement new old stock I think I will just have the same tyre age problem. Anyone know if possible to buy new 12x20 Tubed bar grips. Thanks. Quote Link to comment Share on other sites More sharing options...

Sean N Posted August 19, 2014 Share Posted August 19, 2014 The tester's manual is here: https://www.gov.uk/government/publications/consolidated-hgv-inspection-manual-2013 In fact, the reasons for failure are unchanged: [TABLE] [TR] [TD]A tyre a. with a cut which is deep enough to reach the ply or cords, and is more than 25mm long, or 10% of the section width, whichever is greater. **b. with a lump, bulge or tear caused by separation or partial failure of its structure, including any lifting of the tread rubber. *c. with exposed ply or cord. [/TD] [/TR] [/TABLE] As regards perished NOS tyres, all tyres should be date stamped. Look for tyres which are less than 6 years old. Choose your MOT station with care ... search a MOT Garage with someone that can 'see the sense' rather than just 'read the rules'.... One advantage of VOSA test stations is they do know the score and are very consistent. That's probably why the government wants to close them.

Sean N Posted October 13, 2014 Share Posted October 13, 2014 Tyre black's often used. Don't get the really shiny stuff though, it'll be a bit obvious! TBH if they're bad I don't think you'll pull the wool over the tester's eyes, and if they're not you'll be OK. Quote Link to comment Share on other sites More sharing options...
