TIRE SUGGESTION

If you want the best ride consider using a summer compound tire. You won't be able to drive when it's cold though because the compound will become less flexible.  You also won't need a high mileage tire because as you've discovered the tires will age out before they mileage out.

Tire Rack currently has Vredestein Sprint Classics in stock. I had these on my Speedster and they were excellent tires. Very comfortable, very sticky, and great handling characteristics.

I still would go with a good quality tire as the front of the car is so light you need the best traction you can get.

Has anyone else added weight to the front end of their cars to settle the front end at higher speeds?

The issue is simply front brakes can easily lock up and that happens on the front end especially if you get on a washboard or bumpy road.  believe you have the new 15 gal tank that I helped IM source out to give my car at the time a larger trunk with two radiators.  This helps by adding weight to the front of the car but some people keep tools or have even added plates (metal) to their front end to add weight.

When it happens it is a bit annoying if you have to suddenly stop and the front locks up, and the tires chirp.  ABS?  Maybe someone with experience with an older 911 from that age can comment if there is an issue with those cars as well.

Vreds are good tires...My 1st speedy came with a 60lb bag of sand in front, no issues

I put my battery up front in my Spyder when real estate in the engine compartment got tight. I have my Filter King when my battery used to sit.

"Has anyone else added weight to the front end of their cars to settle the front end at higher speeds?"

A few people on here have added weight to the front of their cars, pushed as far toward the outside front corners as they could.  I think @Jim Gilbert - Madison, Mississippi did something with fancier weights on his car, too.

Usually, high speed lightness can be helped greatly by adding additional caster to the front beam by installing caster shims behind the lower torsion bar tube.

Tell the alignment tech that you want between 5º and 7º of caster after installing one or two shims per side at the bottom of the front suspension beam in order to get your car more stable at speed.  It's best to get an alignment shop to do this, but they won't have the shims in stock.  Buy them and take them with you to the shop.

Get your front suspension set up right first, and if that doesn't make it stable at speed then go the additional weight route.

FYI, He has a 911 front end with a turbo subie  not hard to reach adhesion limits

I second this.  I put the Vred Sprint Classics on my speedster 2 years ago.  I've been happy since.  I replaced the Pirelli's that came with my car.  The sprint classics are so comfortable.

I need to replace the 165/15 tires on my Intermeccanica speedster. Plenty of thread, but the car sat for at least 15 years, and they are over 20 years old. I don't expect to drive more than 5,000 miles per year at the very most. I live in Sacramento so I don't have to worry about super cold weather. And I won't drive it in the rain. Don't want to spend a fortune, they don't need to be high performance. Should I consider used? Basically, looking for your input on best quality for an affordable price. thx

NO!

Tires are like steak to me. A cheap cut gets it done, fills the belly. Not in any enjoyable way.

Nothing like a good steak, though.

Things I won’t buy used: Shoes, toothbrushes, and underwear. Tires? Generally not, but I did find a good used set of Michelins for my ML for $100. (Hard to find and expensive 275/55/17) Sold by the owner of a tire store who said he replaces his wife’s tires when they’re at 75%.
