Hello everybody! I'm trying to put on a road my new toy - R688 E6 -1988. It has lots of problems including custom-built 20 inch wheels. They welded of russian KrAZ-KamAZ pieces and are of triangle form now. Tyres are completely dead that makes together horse-riding drive from 40 km/h up to 90. Truck was originally fitted with 24,5 Alcoas (and came on them in Russia in 1994). There are 2 of them survived, has Alcoa number 983101 and located originaly in front. During my research I found some Freightliner 24.5s (just no Macks in Russia :( ) and some people ready to import used wheels from America. The matter of question: looking in the net I noted hub or stud piloting. I suppose there is no difference to use in front, but what's in the rear?
