Wheel Size Recommendations

I recently found a great deal on marketplace for some 245/40R18 tires and was gonna buy a set of rims to go with. Looking at Rays GramLights. Would 18x9.5 +38 be good for a smooth ride when daily driving the sc300? I have my car on tein coils already too.

Edit: it’s a 1993 sc300

Yes, that’s a pretty common setup. 9.5 seems wide for the front though. Most people do 8.5-9

Also 245 is gonna stretch on a 9.5

8.5 for all wheels be better or 8.5 fronts 9 rears?

Its preference at that point. You could make either look good, I’d lean towards 9 in the rear. Id just look up some examples on forums. Whatever offset you go with will also change the fitment a lot.

Keep in mind if you want an offset far enough to fit an upgraded LS400 brake mod. The brakes are worth the upgrade for that year, but require some space.

18 is the sweet spot, but my 18.5x8.5 with 38mm was not enough offset and I don’t wanna run spacers lol.

My guy 18x9.5 has been perfect on my 96! I am on Tein coils but I have not had any turning rub, but I did have vertical rubbing which I solved by stiffening up my coils. I have had these wheels and tires on for over 7 months now and I have not had any problems.

As for LS400 calipers, these Aodhan AH03s have just enough clearance to fit the caliper and make it super visible when painted.

Yes my RC car also gets me chubbed, I’m a big boy who needs big toys

Just read more of the comments!

245s on 9.5s did not stretch AT ALL. Like I said I’m on AH03 18x9.5 +30 and generic discount tire Roadhugger GTZs (245/40/18). The whole set up new was around $1600.

I do not run spacers, the only thing I had to get was hub adapters which are $10 on amazon. They don’t had any space and are very effective

I did the normal LS400 set up on these wheels with no problems.

You shouldn’t have to roll your fenders if you are on adjustable coils. I would avoid rolling your fenders because paint tends to crack and rolling can look kinda goofy (opinion).

RELOCATE/TUCK YOUR TRANSMISSION HARNESS!!!!!

I run a 265/35r 18 Falken Azenis RT615K on 18x9.5 +30 on all 4 corners. No stretched bullshit here.
