the inner tubes available today are very thin compared to ones that used to be used and they will puncture easily .
do youre tyres have small diagonal ribs inside , most landy tyres do , if so then this is the root of the problem, the ribs rub against the tubes and eventually puncture them .
rarely do i get a true puncture which is down to an object picked up through wall of tyre , it allways seems from within the tyre itself .
check youre tube next time to see where the puncture originated from within the trye/wheel .
i have had many a puncture in the years ive owned landrovers/rangerovers and its allways the same problem , i got used to it and it only costs me £5 to get them repaired or have my new tubes fitted .
i tend to use remould mudtrack tyres and am aware i dont have the best options , but price is important .
it doesnt matter if you use steel landrover/ steel rangerover rostyle or rangerover classic ali rims , they all do the same thing .
i have sandblasted and painted the rostyle rims , they are better now but ive still had 2 punctures in the last year since new tryes placed on them , it usually comes hand in hand with driving longer distances than just a few miles , ie you get home after a trip out and the the next morning find you have a flattie :-(( !!.
i buy a few spare tubes every so often and when i get a puncture i just have a new tube fitted . i think tubeless are the way to go though and would be insterested as to what others use in the way of rims and tyre combinations .
i used to use weller 8 spoke rims with tubeless 31x10.5x15 armstrong norseman tyres and only ever had one puncture .
