Tire size

[svt 500]

I'm thinking of going with the Toyo R888 for the rear and since they don't make the factory size in the 19 for the front, I'm thinking of going one size up. Any problems with a 275 vs 265 and if no issues, is it best to keep the 40 series with the 275?

What's the difference between a 275/40/19 Y101 tire and a 275/40/19 Y or Z 105 ?

275/40 looks too bulky up front.
I personally don't like the look of the 40 series up front, but I'd suggest the 255/40 over the 275/40 if you're not willing to run the 275/35/19.
Interestingly they make a 285/35/19 front too, wonder if that would fit?
Which rear R888 are you running--285 or 315?

OP, what size did you go with up front? Curious to see what the 40 series looks like vs the 35

I'm running Michelin PSS 275/40/19 up front. No problems and the tire looks fine.

Did you have to get new TPMS?

I'm running 285/40-19s up front with no problems. If you run a 35 aspect ratio with 20s in the back, it's going to be too short. The difference in tire diameter between a 35 and 40 aspect ratio with a 275mm cross section is going to be over an inch.

No I didn't. No problems.

Thanks. I'm changing all 4 tires on my shelby from 265 to 275 front and from 285 to 295 rear this weekend and was concerned about the tpms light.

What 295s brand did you buy for the rears?

Post up some pics when you get them installed.

I did 275/40/19 fronts and 295/35/20 rears with Michelin Pilot Super Sports.

Thank you Pete for the pics. Michelin don't seem to bulge out that much from the rim. You satisfied with the look and feel?

I've got MPSS 295/35/20 NO (Porsche) 105Y for the rears. They are wider than 101Ys and they are more like 305s.

Where are you guys getting your 295/35/20 MPSS? DT is always out of stock and I'm hesitant to consider used.

Yes, they look great and feel like they should have been the OEM tire fir these cars.

I got mine from a local tire shop. Tire Rack usually has them. They will ship to an installer in your area if one is available.

I gave up and bought a used set off of ebay. I couldn't find 105Y K1s anywhere.

Just got the Ferarri version from my local Les Schwab in Livermore, CA. The shop was awesome and called the distributors almost 3 times a week until he found them. Took about 6 weeks, but he found 3 randomly at the Nevada distributor.

They also mounted 4 sets of M/T on my F150 to find the biggest tires that would fit for me.

Great shop, great customer service. Find a shop that doesn't sigh when you ask a lot of questions and gets excited about your tires with you, haha.
