With a wodge of cash in my bank just aching to be used properly, my search for a GTR is finally underway (5 years since I sat in one in the Nissan Boutique in Ghinza Tokyo as I was living there when they were launched) and while that is happening I am scouring this amazingly informative site gathering as much information about these awesome machines - the downside of that is it is making the search/buy lag painfull!
Have many many questions but I'll start with this one (I did try a search but couldn't find precisely the information I'm looking for).
So, are ALL GTR tyres inflated using nitrogen? I understand the physics behind this but in reality has anyone simply used good old normal air?
If nitrogen filled how do you guys cope with the small pressure adjustments that must surely be needed? Are nitrogen filling outlets readily available?
Thanks for reading!
