Despite what the Army said I would not drive on Wolfs on the std studs. The Army had a problem they had to solve and they had no money. They came up with a fix that had no enginering basis but stopped the complaints. It didn't and won't stop water sitting in the thread or people looking at it and wondering about the driver. The 50mm studs (std are 45) fit Wolfs perfectly and are £0.95p each so its under £5 a wheel. They can be fitted in situe with a ball joint splitter in under 30 mins a hub. Anyone argueing to run under length studs to save £5 and 30 mins per wheel needs to think carefully about what they are fighting for.
