david56 Posted April 26, 2019 Share Posted April 26, 2019 Hi. I have been considering changing the tyres on my truck. On Ebay there is a set of wheels and tyres I am keen to try They are fitted with “Run Flat Inserts” what are these? do they effect the maximum speed when used on the road is there any downside to using them Are all ten stud wheels interchangeable. Many thanks David. Quote Link to comment Share on other sites More sharing options...
naaficook Posted April 26, 2019 Share Posted April 26, 2019 The inserts are there to press the side of the rubber to the rims. the make sure the rubber tyre "sticks" to your steel rims. Quote Link to comment Share on other sites More sharing options...
radiomike7 Posted April 26, 2019 Share Posted April 26, 2019 Are you not confusing bead locks with run flat inserts? Bead locks do what you suggest and allow tyres to be run at low pressures for increased footprint in soft terrain without coming off the rim, run flat inserts take up most of the space that would normally be filled with air to enable a tyre to carry the weight if punctured. 10 stud wheels can have several variations, the offset is different between vehicles and they can be either hub centric or stud centric.

radiomike7 Posted April 26, 2019 Share Posted April 26, 2019 If these are for the Maxter you would need to downrate it, the rear axle is plated at 11.5 tons and the tyres are 164 load rated which is 10 tons for the pair. Quote Link to comment Share on other sites More sharing options...
tankdiver Posted May 29, 2019 Share Posted May 29, 2019 Run flat inserts are fairly very thck a pig to fit it took me 1/2 a day for replacing two tyres, regards Laurence Quote Link to comment Share on other sites More sharing options...
