Hi, currently have the 2021 IS350 F Sport, currently on stock tires. With the refresh having a lower setup(unsure correct me if im wrong) Anyone know how wide I can go with my tires? Thankful for any inputs and ideas.

 

I am not sure whether it's lower, but the wheels are slightly wider than prior years.

We were discussing this over in this thread, as well - https://www.clublexus.com/forums/is-...ck-wheels.html

I think I've seen folks getting away with running a 275, but not sure what else had to be done. Honestly, with the 350, the 265-width tires are going to provide pretty good grip as it is. If you put some nice PS4Ses or other grippy tires out back, you should be just fine with the stock size. If you are wanting a more flush fitment, specifically, then and only then would I say it's worth it to go wider.

 

You want thicker or wider?

Honestly, for the 300/350, the 265 are enough, you could go 275 for a lil wider tire.

 

Thanks for the reply, will check out that thread.

Will also check out PS4S, I hope installing 275s on the IS didn't require extra work.

 

My bad for not being clear I don't know how to word it properly, I guess I'd want to go up in size from the stock tires? 225-235 Front 265-275 Rear for example.
Thanks for the input, any ideas on how how thicker you could go in the front wheels?

 

Stock is 235/40-19 and 265/35-19. You could go 245/40-19 and 275-35-19 without issues. That'll give you 10mm wider tires, and about 7mm taller diameter compared to stock sizes.

Thanks for this! Did you get thicker tires for your IS? Only have PS4S in mind as suggestedby @arentz07

 

Not yet, but that's the sizes I'll go with when I do. And probably PS4S also.
