Good day, fellow Jag-Lovers. Long-time contributor over on the E-Type forum, but a relative newbie on the Saloon forum. I’m bringing my 1961 Mark IX out of its 30+ year hibernation, and I’ll be having a lot of questions to pose in the coming months. While I’m quite conversant on the E-Types, I recall very little about the big saloons… I used to correspond with Larry Martz (RIP) back in the day.
On to my first concerns. I’ve just purchased a set of P225/75 R16 tires for the Mark IX, which of course are much wider than the 6.70 inch originals. Clearance under the wheel wells should not be a problem, but now I’m curious as to the width of the stock rims. I’m sure that information is in my factory manual, but those are in storage (somewhere). Secondly, I was counting on the fact that since the wheels are steel disc type, that I could run tubeless with the “modern” tires. That may not be the case, however, so I thought I would pose that question here as well.
I’d appreciate any insight you could contribute regarding issues in installing these tires to the original steel wheels. Thanks! Jay
