thinking about going with 18s, tsw slot to be precise. I think I mentioned that in another post and the tires.com guy told me 35mm offset would fit. several people then said no it probably wouldnt. the other offset is 45mm. what is the stock offset and will this 45mm offset fit? I really like those rims. they remind me of the hre 545s but are far less costly.

 

Acura 18's have 45mm offset 18X8.5

 

45mm is your factory offset.

 

the 18's are only 8'' wide not 8.5''

 

Wrong. I called the dealer to confirm they are 8.5". Another member on here also states that the wheels say the size (8.5") right on the wheel.

 

The Acura 18's do say they are 8.5 wide and if you choose to measure them they are 8.5 from bead to bead and 9.5 from edge to edge. I have an unmounted set on hand, so this info is as good as it gets.

 

Will rim that are 18x8 w/offset 43mm fit on the TL?

 

Sure, They should fit. That's only 2mm less offset than the ACURA wheels. 2mm only equals a smidget if you look on a scale (measuring stick)
