Just bought my First 911

It's a 1987 Carrera Targa with all the books and records, etc. I live in Florida and it's a local car, the good doctor who sold it to me just has not had the opportunity to drive it very often, since he bougth it a year ago. I'm going to impose upon this group as I'd like some recommendations as to tires, the Dunlops appear to be about 80% worn in the rear and a tad less in front. I'm a senior citizen, my first car was an MG-TC which my dad provided me in my Senior high school year, next was a 1952 TD Mk-ll which I raced several times. I owned the first Healey 100-4 sold in California and raced it in several SCCA events until I got my first XK-120 and move to C production. Since then it's pretty much been a series of Jags but now I've added the 911 to the stable. Confession: Last Porsche I drove (before test driving this 911) was a White 1955 Speedster that my then-girlfriend bought off the showroom floor in Sacraemento, CA, she paid around $3000, and when I drove it my knuckles were white every time I approached a curve. More later, thanks for any feedback and regards, Barry
