Hi
I'm working on getting a 2019 LC 500. It has run flat tires--is that a good thing? Would regular tires be better for this car?

 

regular tires will likely be quieter and smoother and probably handle better too depending on the tires, but obviously you run the risk of a flat tire.

I have the factory installed non runflat Michelin PSS5’s on my ‘24 vert.

They provide a very quiet and smooth ride.

The car tracks on the highway (125 - 130 kmh or 75 - 80 mph) like it is guided by radar with absolutely zero pulling or tram-lining.

I drive my car as the GT that it is and these tires are really capable and comfortable, contributing to the sporty luxurious character of the car.

They are very quiet!

They’ve performed as I would expect in the limited rain that I’ve experienced; no slippage or insecurity.

I’m very pleased with the Michelin PSS5’s and I’d highly recommend them.

 

are you sure they are run flats?

 

The PSS5’s are non run flats.
I’ve read PSS4’s are also an excellent non run flat tire.

 

Yes exactly, these are best trackable street tires as well. Not run flats. Mine came with Dunlop run flats, I’m going to replace them with PSS4 / 5 when these run out. Michelin makes the best tires, period!

 

Super happy with my Pilot Sport All-Season 4s. They don't handle as well as the summer Pilot Sports obviously but still much better than the Dunlop run-flats, & I like to be able to drive in below freezing temps.

 

What sizes did you go with?

 

I assume you have 20’ rims? It doesn’t look like Michelin offers the A/S 4 in the LC’s 21’ rim size.

 

I think most just upsize the fronts to 255/40 21s.

 

24 LC Dunlop Sportmax 60, great all around tire, quiet,comfy ride, no issues with me till they wear out.. I dont race,track,just mature driving,,Im pleased with them.

 

I got the same on my LC - was hoping for the Michelin PS5s, but thus far the Dunlops seem perfectly fine for normal driving.

 

Curious whether I'll get the Michelin PSS5 or the Dunlops on mine when I take delivery. Fingers crossed for the Michelin but if it's the Dunlop hopefully it's a decent replacement. Likely will last longer than the Michelins.

 

Runflat tires have thick, tough sidewalls that are capable of supporting the car when they are out of air.
They are also heavier than conventional tires.
Adding unsprung weight to a car usually is detrimental to handling and doesn’t help ride quality.
Most readers here are/were unhappy with them.
Last time I changed a flat tire on the side of the road was in 1971. I carry Slime sealer/inflator pump. It takes up space about the size of a shoebox.

 

Well worth it to buy wheel and tire insurance, I paid 2k for 5 years. The run flats are 600 a piece. I had to replaced 4 tires already and will get my bent rim fixed or replaced.
