Ok so here is the story. Not long after I picked up my supra (a few months ago now) I noticed the tyre pressure in the front passenger side kept going down. Now, the tyre was pretty rubbish so I bought 2 new ones for the front (the other one wasn't too good either, but the backs had a new set on, so no worries there). Great, I thought problem solved....or so it seemed.
The next day it was going down again, spoke to a few people and they said as my wheels are right angled valved tyres maybe the valve is busted. So I sought after and found a right angled tyre valve fitted it on...Problem solved... but wait, the next day...guess what, that's right it went down again. So I asked around took it to more tyre places and their theory was to 'check the bead' so got it checked, nothing wrong.
Then one guy at kwick fit wanted to find out what was making it go down (This guy is the only guy who looked at my car EVERY time I went there to query etc) then after about 30 mins of examination he comes in and says "You need new wheels mate". He showed me that the alloy itself has holes in it small pin hols but where the supra weighs alot, having pressure put on it, it decides to come out quicker.
So I told a mate of mine who unfortunately wrote his supra off (Masenko) and he soaid I could have his wheels. Now mine are 17" wheels with 255/40/17 (i think) and I just tried to put his wheels on my car they're 18" with tyre sizes of 2x 245/40/18 and 2x 265/35/18. Put the 245/40/18 and the front and took it for a drive just to test. and when I turn the wheel it gets caught on something (im guessing the wheel arc). So I've had to take them off and put the pin hole wheels back on. Was I correct in putting the 245/40/18 on the front?
Point to note. When I bought the car the guy said it has lowered suspension on it and when I checked the brand it has KYB Street Suspension written on it along with Japanese writing. Is it worth trying to alter the suspension or should I just seek a new set of 17's
p.s. sorry about the long thread, just thought I'd let you guys know all the detail, people on here have always been extremely helpful.
