The LTX M2Ss do feel like a great upgrade, but it's hard to say how much that's the gap between brand-new vs 18k miles and a fair fight between two fresh sets just yet.
As the title indicates, I have a full set of original 20" 275/65 R20 Pirellis available with good remaining tread. I got some new Michelin Defender LTX M/S2s installed purely due to road noise considerations and a good sale. They are in my hangar at Jacksonville Executive/Craig Airport now off...
Hi all, long time lurker and 1st-gen R1S owner here. Thanks to those that recommended the 20" Michelin tires, as I got them installed this morning and they seem to be a great improvement for road noise over the OEM Pirellis.
