I know we all look forward to the day we have to replace our Bullitt's tires. Well, maybe not looking forward to it that much, but.... I have owned a number of Sports cas and Muscle cars over the years and tried a lot of different brands to see how they reacted on the car. I an not quite ready to replace the OEM BF Goodrich 235/50/18's that came on my Bullitt, but am looking to the future (1-2 years down the road).

BF Goodrich, Dunlop, Michelin & Pirelli are on my short list. Since the Bullitt is a more or less daily driver (for now), I will put a good Summer All Season higher mileage tire (300 - 400 tread wear rating good for 20 to 25K miles depending on my driving habits). For some reason I always liked the Dunlop GT Qualifiers back in the 70's and 80's.

Also, I will upgrade the tire size to 255/45/18's to keep the Rolling Diameter the same as the OEM 235/50/18's on the Bullitt now. The RD in now 27.1, so I can stay in the 27.0" to 27.2" RD with the brands mentioned above. (see my response on the "Winter Tire" thread).

So, what are your opinions, 2 cents, etc.... on your choice of tire brand and size for your Bullitt's tire replacement?

the new goodyear assimetrico f1 are my choice after the 275/45/18 choices... I'm leaning to the continental sport contact 2's in that 275 size, as it is the largest size tire approved for our 18x8.5 wheels. It'll be tight in the front, but I like it tight... Hehehe. ;)

I want more rubber on the ground

Well, I would like to keep my 4 original Bullitt wheels, but I would really rather run the same tires I have on the GT500, if I could get wider wheels that look like the originals.

Here are the GT500 Wheel and tire specifications, and these would fit on your Bullitt with no problems.

5-lug, 4.5" bolt circle
7.125" backspacing
45 mm offset
18" x 9.5" wide


Goodyear Eagle F1 supercar tires
255/45/18ZR 96W Front
285/40/18ZR 96W Rear

I am quite sure that if you could go with more rubber under our Mustangs, they would have done so for the KR's simply for the lateral grip and the traction, but they kept the same size as the standard GT500's.

Who approved them? I know no 275 BFG is listed for 18x8.5 rims.
That's because bfg unfortunately does not make a 275/45/18. Goodyear, perelli, continental, bridgestone, and Michelin do though.

I like bfg as much as anyone, but there's other great tires out there too.

If you check any of those manufacturers sites, you will see that size is approved for a 8.5" wheel.

It's the stock size on a few different amg mercedez.

Cheers.

Some of the tire companies don't like a RD change greater than 3% so thats why there is different information on how much bigger you can go on our 8.5" rims. I'm not sure what correct but if you have a big change the speedo error becomes more of an issue unless you can correct with a tuner.

If you want sticky at all costs go with NITTO.If you want quality and life go with Michelin as they are on all of my daily drivers.As for the post on Continetal tires,Read the forums about how they were sued and lost because their tires didn't come close to the mileage expectations.It may have been only one or two sizes in a certain style but still it bears investigation.
NITTO or Michelin,Nuff said:wink:
