They are S Rated, I'm fine with that, I'll never have the CT on a track.
They have an exact replacement for CT Stock Size which is LT285/65R20.
I was curious, wonder if it has launch performance effects as well.
There are three models in their parts catalog.
May I ask where you got the tires from?
Thank you for putting this together/sharing.This is the thread on this Tire I would have like to have read but not much is out there. A couple kind members here have them and I've enjoyed reading their notes. The AT's were great through the winter for me but they are noisier than I'd like on the interstate. Most of my driving is City/Interstate with only occasional off-road. The Truck is so quiet I wanted more of that. I wanted to soften the ride a little, /possibly/ increase Interstate speed efficiency, reduce the noice considerably and perhaps have a little better traction than the AT's. I decided to give the Michelin Defender LTX Platinums a try on the stock wheels. Over all I like the way they look, still aggressive but with a more traditional sidewall. I've had them mounted since March 4th, they were properly Road Force Balanced by my local tire shop I've had a long relationship with.
Findings after 3 weeks and 725 miles driven on the Michelin Defender LTX Platinums:
- Right out of the gate they were quieter than the AT's
- My steering squircle was not centered (ever so slightly left cocked) after getting the vehicle back from the tire shop. They did observe the proper lift points (I printed out the manual page, handed it to them and showed them where to lift). I drove it on the lift myself and put it in Jack Mode. They did NOT attempt to align it on my request. Tesla did align it at the service center and all is well ($295 bucks later).
- The ride is softer than the AT's
- When tuning these tires for quietness, Air Pressure matters. They roar at 47 PSI and at 53 PSI but tends to be most quiet dead nuts on 50 PSI. Oddly though, temperature swings affect this tire more than the AT. 47 PSI at 45 degrees Fahrenheit and 53 PSI at 80 degrees Fahrenheit on Blacktop. I haven't tried it at 60PSI like another member here mentioned. The tires still have a little roar / roar/resonance/warble but not as much as the AT's. Something like half the noise of the AT's which is nice, I hear the Tesla motors more with these than I did with the AT's.
- They don't (at least at this time) seem to have as good of dry traction as the AT. I notice it in hard cornering and Beast Mode launches. Hoping this will improve as they break in a little more, but doubt I'll see much difference. Not a deal breaker but may cost you a Tenth of a second or two on blacktop in a Bestmode lunch.
- Wet performance seems to be very good.
- The Michelin's appear to be more energy efficient than the AT's.
- Stopping seems great, no issues.
I have a Tessie Subscription and posted a few metrics. In this case on the first two images, I've filtered out all city/short trip driving and showing only interstate drives. If you know Tessie better than I do, by all means suggest other metrics:
Michelin Defenders - March 14 below is a 160 mile round trip. FSD most of the drive kept around 73mph
Stock AT Tires - March 3rd below is a 170 mile round trip of interstate, FSD at around 73 mph.
Below is all drive data for the entire month for the last 3 months.
