Fernando- Problems with ABS usually start in the 4-5% range difference from OEM.
I'm going to order the Michelin Pilot Super Sport 235/40R18 and 275/40R18. Hopefully all will be OK. The aspect ratio on the OEM 215 is 96.75mm whereas the 235 is 94mm so the tire is a bit wider and a bit smaller in diameter.
Having read a lot of tire reviews here and other places, I'm putting Michelin PSS on my 16M and taking off the Pirellis. The only issue is availability. The back tires have been backordered on Tire Rack for two months and become available in 15 days. I'm also intrigued with RE11, maybe next time or on the other cars.
I remember you told me that once and I believe you, but I do have ABS problems with 235/40 and 285/40 (ratio 0.94) so that is why I wanted to cover my bases and don't go over +/-1 from OEM 0.96
I recently bought Bridgestone Re-11s in 275-40X18 225-45X18 excellent tyres for max grip in dry weather use case. I'd prefer the Bridgestone Re-71s, but not yet made in appropriate sizing. My speedo indicates 8% fast with these nearly stock size tyres.
agreed I burned up a few sets of the V12s on my 993. Good street tyres but get greasy fast at the track.
That is OEM+1.32, my setup is exactly OEM-1.95 and I do have ABS problems (too sensitive) Thanks for that info. Have you felt like the ABS is too sensitive when you are braking to exit a freeway or so???
I got on the wait list for front and rears for my 430 in February for what they said was a six week wait, got em in one week and have been on the car for about three weeks. Replaced my 10 year old PSS. If you are not on the list you should it might speed things up.
Definitely a plus for RE-11. I have stock sizes and they are without doubt the best performance tires I have ever used on performance cars. Super grip on dry roads (I feel absolutely confident in what the car will do) and fantastic in slippery conditions. In mountain driving, we have been caught several times in torrential rains and even pressing, the tires are great. I'm putting a new set on my 360 in a couple of weeks. One thing about the fender damage issue. I have pranged my left front fender twice, and the right once in hard mountain driving. In trying to figure out why, I learned that specs for tire sizes are pretty wide, so you may have a bigger tire than you thought. On tread life, the rears on my car have gone 17K miles and are now in the red. The fronts have gone 11K and have 5mm tread. Hope this helps. Cheers, Andy
Pretty hard to make a decision between RE11 and MPSS, it seems like the votes are 50/50 Sent from my iPhone using Tapatalk
If you're putting around in a Camry, I suppose you could go with 10 year age limit. Personally, on any sports car where you're going to be doing spirited driving - I would not risk it after 5-6 years beyond the date code stamped on the sidewall. What's another $3-500 when you're ultimately talking about your safety and peace of mind?
True Another factor to consider is WEIGHT RE11 is an older technology and the tires are heavier. The OEM 215/45 And 275/40 RE11 weight 26 and 31lbs Michelin PSS 235/40 and 275/40 are 23 and 27lbs 14 lbs of unsprung rotating mass seems like a lot. Here is an interesting article about unsprung rotating mass Ferrari 360 Wheels | Aldous Voice If OEM starfish wheels are 9.7 and 11.4kgs total 42.2kgs (92.95 lbs) And Challenge wheels are 8.6 and 10.5kgs total 38.2kgs (84.14 lbs) Standard steel bolts 128 grams X 20 = 2,560 grams (5.64 lbs) Titanium bolt 65 grams X20= 1,300 grams (2.86 lbs) So the challenge wheels along with titanium bolts save 11.59 lbs I have race oriented RAC Monolite lightweight aluminum forged wheels that weigh 19 and 20lbs (3,600 dollars) and titanium lug bolts (600 dollars), assuming the bolts in the article weigh the same than mine, my car has $4,200 invested to save 17.73 lbs of unsprung rotating mass (98.59-80.86) and adding that weight back with a heavy tire doesn't seem like a good idea. Disclaimer: I purchased my car with those wheels and bolts, I would have never invested that much money to save 17.73 lbs, but if the challenge car came like that, it is something to consider,
Does anyone know how the Bridgestone Potenza RE 050 A compare to the RE-11 or other tires that have been mentioned in this thread? I recently bought a 360 spider and new tires had to be fitted when the car was serviced before delivery. Based on what I had read on this forum I hoped that RE-11's could be fitted, but it seems that Bridgestone is not selling these tires in Europe. It also seems like the RE 050 A's are about the only tires available in Europe in OEM sizes.
A short internet search seems to show indeed that the Bridgestone Potenza RE-050A and the RE-11 are not in the same league, although the same search also suggests that the Potenza 050 was fitted as stock tires on F430's. I hope that someone here on this forum can comment on the difference in daily life between these two Bridgestone tires. I'm still having a hard time identifying high performance tires for the 360 in Europe that come in OEM dimensions. Would I be an idiot to consider the following? Front: Yokohama Advan Neova (AD08R) 215/45 R18 89W Rear: Michelin PSS 275/40 R 18 99Y I know that the speed rating on the Yokohama tires is incorrect if I wish to take the car to its top speed. I think I'd be willing to give that up in exchange for significantly better grip (its a spider, I would like to keep my drivers license anyway and I do not think that I will drive the car on race tracks). BTW .... I just noticed that the dealer who put new tires on the car just before I collected it last week also put W rated front tires on the car (Potenza RE-050).
Michelein PSS 300 is the way to go. Stickiness at all temperatures including wet. If you truly want to keep the rubber on he road buy them and call it done. BTW IMHO never buy a tire/tyre promoted by a British spokesperson. You know I'm talking about Hancook tyres. These F cars are not ricers. Have some friggin' class.
Never mix brands and treads of tyres, especially on a performance car as it can make for some pretty unpredictable handling characteristics. Besides it will look ridiculous with two brands of tyres on the car. Use the same make and model. Get MPSS on all 4 corners. 225/45R18-275/40R18 will work. It only deviates in front to rear difference by about 0.8%. You will be hard pressed to even tell the visual difference unless you know. We're talking about a front tyre profile that is only 0.1" taller than stock. It will also take out some of the understeer of the 360 with a wider front tyre.
235/40 and 275/40 are actually closer to OEM ratio, and I can confirm no rubbing at all with that size in the front even in hard cornering.
No they are not. 235/40R18 is 25.4" in diameter and 225/45R18 is 25.9". That makes the front to rear difference deviate by 1.1% instead of 0.8%. OE difference is about 4% with the fronts being 25.7" and the rears being 26.7" in diamtere, the 225/45R18-275/40R18 has a difference of about 3.2%. The size you suggest has a difference of 5.1%.
I think you are making wrong calculations, just include two decimals. OEM 215/45 is 25.62 and 275/40 is 26.66 so 25.62/26.66=0.9610 225/45 is 25.97 so 25.97/26.66= 0.9741 235/40 is 25.40 so 25.40/26.66= 0.9527 0.9527 is closer to 09610 than 0.9741 The starting point from where you measure the difference is OEM 0.9610, not 1.00, when you say mine is 5.1% and yours is 3.2% difference you are measuring from 1.00, and mine is actually -0.86% and yours is 1.36%, either configuration is pretty close and both will work. Closest would be 225/45 (25.97) and 285/40 (26.98) 25.97/26.98=0.9625 (0.15%) and you could compensate the speedo error a bit but only continental tires are available in that configuration.
After so many helpful replies I can say we have three main options. Two tied in first place and one just below. 1A Bridgestone Potenza RE11 in stock 215/45 and 275/40 (Track oriented but heavier and older technology) 1B Michelin Pilot Super Sport in 235/40 and 275/40 (225/45 would work too if you don't want to go that wide in the front or can't find 235/40) Lighter and newer technology but not as extreme as the RE11 Both tires are ranked 1st in its category 2 Continental Extreme Contact DW 225/45 and 285/40 (this bigger rear tire will help a bit with the optimistic speedometer error) Sent from my iPhone using Tapatalk
MPSS work nearly as well as the Re-11s for max dry weather grip, probably better for sketchy weather, but not a problem for you in SD. Either will work well until the Re-71s are available (probably never in our weird rear tyre size) sigh.
I notice no issues with ABS. These tyres worked well at a Chuckwalla track day earlier this year........................
