19 inch alloys

[gaz6963]

Hi guys, could someone answer my question as to wether these wheels will fit my Lexus IS250 2007.

I have found a set of OEMS concave alloys with tyres for sale. They are 19x8.5J, 5x114.3, centre bore is 66.7, sitting on 235/35/19 tyres.

Will these fit straight on my car or will I need coilovers?

Thanks in advance for your answers

I believe that centre bore for lexus is 60.1, so 66.7 will clear, but I am not sure if having oversize bore is good - maybe someone with more experience on aftermarket wheels can comment.

The pattern is fine - 5x114.3, but if I understood you correctly the set you looking at is square 19x8.5j? I don't know for sure, because you have not provided offset, but it looks fine. 6.3mm should not have major impact in front and will certainly be ok in the rear (standard tyres are actually wider). For reference OE offset is ET45/50 and once you have your offset available you can check yourself using page like this one: https://www.willtheyfit.com/

Just had a look and the offset is 42

This make the fronts 9.3mm closer to the arch, my guess is that fronts could scrub, but rears should be ok (~8mm wider). You could do your own measurements and see how much you have from original wheels and whenever the difference can be accomodated. Perhaps if you get narrower tyres (like original 225s) in front, it would tuck under due to more stretched profile

Hi guys, so went ahead with getting the 19 inch wheels. What I would now like to find out is, what tyre pressures should I be putting in? Tyres are 235/35/19. 
thanks

My RC with similar size wheels is on ~2.4-2.6 BAR
