HELP: Tires Clarification for R19 Wheels.

A quick question to ask about different brand tires on R19 rims.

I bought and collected a set of Performance wheels from PML and now looking for tires. They offered to sell and install for me Bridgestone Potenza 225/35/R19 and 255/30/R19 but a friend is recommending PS2 instead.

But Michelin doesn't come with 255/30/R19. The closest they have is a 255/35/R19.

So does it really matter?

Thanks all.

Re: HELP: Tires Clarification for R19 Wheels.

the RFT sizes are a little unique. but it shld be fine with the slightly thicker tyre wall for te michelin tyres. besides its alot more comfortable and quiet

Upping tire wall means your speedometer accuracy will be affected. Maybe your actual traveling speed would then be closer to the speedometer reading (since german car speedometers are typically conservative).

What are your rim width? Sounds like your front is 8J and rear is 9J only. Most of us are on 8.5J front and 9.5J rear. Anyway, your fren is right to recommend PS2. They are gat tyres. But PS3 is already out. So u may wanna ask abt that from the usual suspects like Hurry, Chin Wah, SouthEast or Leong Seng.

performances 19" rims are 8" by 9" iirc

hence the 225/35 and 255/30

BMW Performance double spoke 269 – complete wheel-and-tyre set*
19 inch, cast. The BMW Performance double spoke 269 sets whole new standards in lightweight aluminium wheel construction using low-pressure casting. This is suggested by the elegant minimalism of its sports-style design, and is confirmed by a glance at the very low diameter of the spokes resulting in considerably reduced weight. For BMW 3 Series. 8J x 19 225/35 R19 Y front, 9J x 19 255/30 R19 Y rear. RSC complete wheel-and-tyre set with runflat properties, tyres: Bridgestone. Not for M3.

Original BMW Accessories : Accessory finder

This is what it is.... you guys are right. It is 8J and 9J. What does that mean?

Actually, I recalled seeing some bro here using the same rims... if you're out here, please share what tyre you using.

Thanks!

if you want your car to be within the BMW factory spec best you stick to Fr 225/35-19 and Back 255/30-19 :thumbsup:
 
Re: HELP: Tires Clarification for R19 Wheels.

i have a related question
can 8.5J take 225 and 9.5J take 255 .... 225 (front) / 255 (rear) are BMW OEM spec for 18"
oem 18" rim are mainly 18x8 and 18x8.5 and aftermarket rims are commonly available in 18x8.5 and 18x9.5
i have asked many tyres workshop like LS, Hurry, etc and they normally recommend 225/255 for 18x8.5 and 18x9.5 rims that they sell
however, based on many posts here 8.5J and 9.5J should use 235/265 width
 
Re: HELP: Tires Clarification for R19 Wheels.

i've read this article and notice that 225/255 tyre width is within the 8.5J and 9.5J rim width limit
i guess have to mount the tyres then can find out whether the "stretch" is acceptable due to different side wall characteristics from different makers

yes for both 18 & 19 BMW OE recommend F225 and R 255
for those aftermarket wheel the rim are generally wider and still able to take OE size as mentioned.
you can always check your tyre sizes recommended by BMW on your front driver door pillar or BMW handbook if you want 101 % safe.

WALAO! Chin Wah quoted me S$2700 for non run flat tires PS2.

I think better stick to BS Potenza... noisy or not don't care already and still get 101% exactly the specs recommended by PML.

Ben, a couple of pointers:

(1) If your wheels are 8J and 9J, the optimal tyre size is 225/255. On some if not most tyres, 235/265 will be too wide to be squeeze onto 8J and 9J.

(2) The tyre width requirement depends on your ride too. Example, if you are running on 8.5J and 9.5J, 225/255 tyres can fit, but it you need more grip on more torque, you can opt for 235/265. So there are actually 2 "optimal" tyre sizes for a 320 vs a 335..... Of course, some cars will go for the fatter look.... For most brands, 245/275 is too wide to be squeezed onto 8.5/9.5J.

(3) Not all tyres are identical in sizes despite the readings. Tyres X's 235 can be same width as tyre Y's 245 given the different shapes in shoulder blocks.

(4) Which Potenza are you comparing to PS2? In the past, S03 from Bridgestone is comparable to PS2. S03 is now obsolete. The successor RE11 is the comparison to PS2 in performance terms. RE11 has harder sidewalls, is heavier but has better grip than PS2.

(5) PS2 has agent price and PI price. They are the same tyres, just from different sources. On 19"s, say 245/275, it should be around $2800-2900 for agent price and $2500-2600 for PI prices.
