What offset is recommended for 18x8 0r 18.7.5 rims on 2001 LS430?
Looking for rims and wondering what offset should I be looking for when shopping for 18x8 or 18x7.5 rims? I was also going with 245/45/18 tires to match closer to stock diameter set up. I used this website to help. http://www.1010tires.com/TireSizeCal...mp;vehicle=yes Will a 18x8 with +38 offset work or 18x7.5 with +35mm offset? Any suggestions and does style matter also?

I think the offset you have would be ok. You can go back to your link and click on "tech section" then go to "wheel offset calculator" and put all your numbers in to see where the new wheels will sit. They should be just about flush with thw fenders and don't need to roll the fenders at all.

So let say stock is 16x7.5 with 45 offset and new replacement rims are 18x8 with 39mm offset. According to the offset calculator in differences, the inner clearance remains the same (the inside of the wheel to the strut housing) and the outer position extends an extra 12mm (position of the outside edge of the wheel). 12mm converted to inches is .4724 inches. Does this mean that the new 18x8 rims will be .4724 inches closer to the fender filling the gap compared to stock and everything else remains the same. How many mm or inches can we extend closer to the fender without having to tuck or roll them in and also and how much mm or inches can we afford to go closer inwards to the strut housing before touching on a 2001 LS430 kept stock. Just want to find the safe zone.
Thanks for your knowledge and input mitsuguy.

all correct on the sizing (at least without doing it myself, it looks right)... Anyways, you can go a littler further, or even a lot further, but then tire size will come into play... I honestly don't have figures on the LS's as far as clearance, hopefully someone who has something similar will chime in here... On the inside, so long as you give yourself a half inch clearance between the shock and the wheel, you are good - you don't need a lot of room there...

My fronts are 19x9 44 offset which is 20mm more outward and are not rubbing with 245/40/19 w/Michelin PS2. My rears are 19x10 49 offset which is 28mm more outward and has no rubbing issue with 275/35/19 w/Michelin PS2. They do filled up the fender very fully and I don't need to roll or cut my fenderlip at all...Hope this help you and good luck...

To me, mine set up is about as tight as you can get w/o rolling/cutting fenders as far as I can see(I have UL w/stock ride height), I want stagger setup hence the front/rear differences.
Actually, the inside of the fronts are only about 3mm to the banana arm and the inside of the rears are touching the protecting boots of the air sacks. But they are fine this way to me as long as they don't touch anything metal or the fenderliner.
I wish I can show you w/pic. but I just don't get the upload procedures here, sorry....
