Ok, i've merged a bunch of 21" tire replacement threads now, so tons of info here.

 

Well I have never done a side by side my experience is this. My LC originally came with Dunlop RF tires and I tracked it when these were relatively new (less than 5K miles). I tracked my replacement Michelin RF tires with about 2K miles. There was noticeable less understeer with the Michelins. This makes them better in my book. Between these two track sessions I had the opportunity to track a LC with Michelin PS4S. Although not side by side, on track they felt very similar to the Michelin RF tires.

I wasn't driving hard and my first indication was the TPS on the dash. A couple screws had gone through the sidewall of my right front tire and it lost air pretty rapidly. As I slowed down to find a safe place to pull over on the two lane my right rear TPS indicated low pressure. After I stopped and examined the issue I noticed multiple screws in all four tires. I was about 20ish miles from home so I proceeded cautiously (50-60mph) for the trip home. Left front TPS indicated low after about an additional 5 miles. Left rear never lost pressure. Honestly, there weren't many curves on the way home and while it was noticeably a rougher ride, I never felt unsafe.

 

if i'm not mistaken the runflat is designed to hold at around 16 psi...enough to get you home if you take it easy

 

I believe you are mistaken. It’s hard to hold 16psi with a hole in the sidewall. RF tires are designed with a reinforced/stiffened side wall that supports the tread even with zero psi.

 

thanks for the illumination - they are even better than i thought

 

DRGibbons, thanks for your posts on your experience with RFs! Great info.

i'm impressed you've had your LC on a track a couple of times!

Bummer about the screws but a pretty great example of why RF tech is helpful... obviously had they not been RF you'd have needed a flat bed to get the car home or to a shop.

 

Run flats will get you limping home and enough to get em fixed. With that feature they are made a very durable material, especially the sidewall!
Keep in mind u folks with Lexus Enform it offers you a service and or flatbed ride or if you have AAA, will be there to help. So I am about to replace my RF's with the conventional Michelins Pilot sport all season rads. I am looking for more miles, quieter ride with descent handling as I am not a pin the needle guy so the spec on these sneakers will be efficient. I will have to go to the 255's on the front, as there are no matches in the Michelins at present that will replace our 245 RF's at present.

 

Anyone tried PIRELLI P ZERO all summer tires yet?

 

They came stock on my Mustang (different size of course), and the previous owner put them on the front of my LC. I don't have any basis of comparison for them on the LC as I haven't run anything else yet, but FWIW I wasn't impressed with them on my Mustang. Less grip and more noise than the Michelin Pilot Super Sports that replaced them. I'm excited to switch to Michelin Pilot All Season 4s on my LC as soon as these wear out or temps get closer to 40F where I live.

 

I also will be going to the all season Michelins 4 not the 4S

 

yeah in case this is in reply to me above, I meant “All Season 4” plural (set of 4) since there’s no such thing as the A/S 4S. 4S usually refers to Pilot Sport, which are summer-only.

 

Gotcha V8n8, I also am looking for the better milage tire which the all season 4 tire gives.
Regards

 

DRGibbons, thank you!

 

I live in NoVA, about 25 miles outside of DC. Last three years, my winter tires have touched snow twice, and only because I wanted to try them in snow. In the DC area, everything shuts down when it's about to snow. As a native Chicagoan this place is a comedy show. The federal government closes down at the slightest risk of bad weather. Then the grocery stores run out of bread and milk and then every shovel, (spade,etc.) at Home Depot is sold.

While I will always own summer and winter tires, the reality in the DMV (DC, Maryland, Virginia) is that unless you have to drive someplace, most people stay indoors.

 

Thank you for patience for what may be a dumb question to some.
I've had my 18 LC for 10 days now. Already have a nail or something in the left rear tire.
😡
I have an apt at Disc Tire this afternoon to hopefully plug/patch. But, I also need a Plan B.
If the nail, whatever, is where it can't be repaired... I've done some reading and I Think I've seen where the Michelins are slightly preferred. Of course, I have Bridgestones on it now.
Should I mix the 2 brands on the rear or not?
Thank you in advance.
