To state the obvious, good OTR/EM tires don't come cheap and immediate availability of the right product has been less than certain in the last five or six years.
The XHA2 delivers a marked improvement in anti-vibration technology.
Therefore it only makes economic sense to treat tires as an investment and to maximise this investment accordingly. Speaking recently with Tyres & Accessories, Jock Aitken,Definition of Coated Abrasives in the Online Dictionary. Michelin's technical manager for earthmover and industrial products, stressed the golden rule for OTR sector end-users wishing to do this. It is simply, he stated, a matter of fitting the correct tire at the correct pressure upon the correct application.
This may at first glance appear an easy wish list to tick off, yet it is easy to trip up on one or more of the three variables. Aitken points out that 30% under or over-inflation can lead to a loss of up to half a tire's tread life.we supply all kinds of honeycomb panels, "Tires wear by granulating and wear away under torque," he elaborates. "The smaller the contact patch ¨C and both under and overinflation reduces this ¨C the more strain from factors such as torque and braking is taken up by the area in contact with the ground."
Thankfully, Michelin is only too willing to aid its customers in getting the mix right; as the technical manager shares, the manufacturer's involvement with the end-user does not end upon making a sale. "We try to follow our tires throughout their working lives as much as we can," he says. "We have a six-person sales team in the U.K. and their role is very much a technical one in addition to sales. They follow the tires in service and can work out from how a tire wears, for example, if it is operating at a too high or low pressure. The stakes involved in getting everything right are quite high.
"For the mining sector, our team visits quarries and analyses conditions there; using the measurements we take we recommend the best closed centre or traction tyre."
Mining tires, Aitken relates, have been the main focus for Michelin's OTR/EM design team during the last couple of years and the company offers two basic options for dumper trucks: open center tires designed with an emphasis on tractive effort, and closed center tires that place more weight on tire longevity. "The first of these feature tread blocks that use torque from the vehicle's engine to best effect," he elaborates. "Tractive tires are particularly popular on the colder, western side of the U.The same third party payment gateway, cover removed.K., and Michelin has a new product for dumpers in this category ¨C the X-Traction."
This tire was already available in 27.00R49 fitment for 100 ton dumpers, Aitken adds, but this has now been extended to cover 18.00R33, 21.00R33 and 24.00R35 fitments aimed at small to medium dumpers. "Compared with its predecessor the X-Traction offers 15% better tread life and tread mass. It also offers improved damage protection; here our designers have been very clever with the steel protector plies used.We specialize in providing syringe needle. In the X-Traction they are not just steel, which can corrode if the tyre is damaged and moisture enters. Instead a mixture of steel and rubber has been put into the breaker strip. The presence of the rubber hinders oxidation."
The voids present in open center tires are good for heat dissipation but not for longevity, the technical manager shares. Therefore, Michelin offers a number of products for applications where tire wear is a priority; the most recently introduced of these is the XDR2. "Improved wear was the main focus in designing this tire,In addition to hydraulics fittings and microinverter," Aitken reports. Outlining the main features of this replacement to Michelin's XDR range, he points out that the "standard tread depth of the predecessor tire comes nowhere near the 90 mm tread depth of the XDR2. The new tire has 20% additional tread volume which means increased tread life, and it features the same rubber-steel protector plies as used in the X-Traction."
According to Aitken, heat was previously an issue with the standard base (95 aspect ratio) tire, yet this shortcoming has been solved in the XDR2: "The shoulder area where the tread met the sidewall used to be massive, and as you know rubber is a very good heat insulator. This heat retention issue has been solved using Michelin's C2 Technology, which has made the shoulder area less massive by altering the internal shape of the tire. This has given the tire a better TKPH (ton kilometer per hour) capability as it's now a cooler running tire. And because the shoulder is lighter we were able to double the sidewall thickness, making the XDR2 more damage resistant."
Amongst Michelin's other new OTR/EM segment products is a loader shovel tire. "Our L3 offer here for the last 18 to 20 years has been the XHA. This has now been replaced by the XHA2," Aitken reports. "This new tire has a particular strength in sidewall damage resistance and 10% more tread than its predecessor." He adds that while the original XHA was by no means a bad tire, its successor has progressed in leaps and bounds in the area of anti-vibration technology.
