It may be a bit rude to ask but have you checked if the wheels are round. To test just jack up the axle close to a wheel until the tyre clears the concrete by 1mm then rotate the wheel and check if the gap remains at 1mm. Eric.

A common but frustrating fault that has plaqued Nissan's for some 20 odd years. Some do it, others don't. It is related to tyre/wheel balance and out of round and usually raises it's ugly head when tyres are changed or rotated.At least, that is the common denominator. Tyres need to be stripped off the rims and inspected internally for bubbles,delamination, balance, out of roundness. Same with the rims, they need to be balanced without a tyre and again with a tyre and even then, rotation of the tyre on the rim several times to get the "high/heavy" spots to counteract each other. It's a long,expensive process that Nissan dealers will not have the time for. You need to find a freindly tyre store that is prepared to spend several hours searching for you, and even then, you have to be prepared to scrap tyres and replace them, even though they look good.
Welcome to motoring, Nissan style. If you have access to another set of rims and tyres, give them a try and at least this will confirm that it is a wheel related problem that has gone on far too long with this vehicle.

I had a similar problem when I changed from the original HTs to BFG ATs. Nothing seemed to help despite 3 or 4 balancing efforts by the company that fitted the tyres. A friend suggested a Bob Jane T-mart gold balance might do the trick - and it did. Now have 50K on the tyres and the problem hasn't raised its ugly head again. From memory the gold balance is about $25 per wheel but well worth it.
