On my VW Passat B5 tires, there is a marking that reads "195/65R15 91 V".

What does this mean? Do I have to get replacement tires with this exact marking on the side of the tire in the future or not? And if not, how can it differ?


Not a duplicate as the other question is incomplete as it just tells the size, this covers the other markings too and gives more in depth, complete answers.

    @Zaid except that the other question is incomplete as it just tells the size, this covers the other markings too...

  • @Nick C I agree and have updated the question (as prompted) to reflect that. Commented Jan 7, 2016 at 20:25

    Which makes the other question a duplicate of this. Then again, I'm probably not the most neutral party in this...

    @SQB Its funny that at this point in time you have over half your reputation on this site from that one answer alone! Well done! Commented Jan 7, 2016 at 21:38

The tyre code is as follows:

  • An optional letter indicating the intended vehicle class.
    Your tyre doesn't have one (or you omitted it) but it should be a P for passenger car.
    Possible values are:
    • P for Passenger Car
    • LT for Light Truck
    • ST for Special Trailer
    • T for Temporary
  • Digits before the slash indicate the tyre width in millimetres.
    Your tyre has a width of 195 millimetres, which is a little over 7½ inches.
  • Digits after the slash indicate the height of the sidewall as a percentage of the width.
    Your tyre has a sidewall height of 65% × 195 millimetres which equals 126.75 millimetres or about 5 inches.
  • The letter after that indicates the type of tyre.
    Your tyre is an R for radial.
    Possible values are:
    • B for Bias Belt
    • D for Diagonal
    • R for Radial
    • If omitted, it's a cross-ply
  • The digits directly after that letter indicate the diameter of the rim in inches.
    Your tyre is mounted on a 15 inch rim.
  • The digits after the space are the load index.
    Your tyre is rated for a load up to 615 kilogrammes (1,356 lb), which is per tyre. Assuming four tyres, that comes to a maximum total weight of 2460 kilogrammes of your car plus everything in and on it.
    Possible values range from 60 for 250 kg / 550 lb to 125 for 1,650 kg / 3640 lb.
  • The letter after that is the speed rating.
    Your tyre is rated V for speeds up to 240 km/h (149 mph).
    Possible values are:
    • A1 for 5 km/h / 3 mph
    • A2 for 10 km/h / 6 mph
    • A3 for 15 km/h / 9 mph
    • A4 for 20 km/h / 12 mph
    • A5 for 25 km/h / 16 mph
    • A6 for 30 km/h / 19 mph
    • A7 for 35 km/h / 22 mph
    • A8 for 40 km/h / 25 mph
    • B for 50 km/h / 31 mph
    • C for 60 km/h / 37 mph
    • D for 65 km/h / 40 mph
    • E for 70 km/h / 43 mph
    • F for 80 km/h / 50 mph
    • G for 90 km/h / 56 mph
    • J for 100 km/h / 62 mph
    • K for 110 km/h / 68 mph
    • L for 120 km/h / 75 mph
    • M for 130 km/h / 81 mph
    • N for 140 km/h / 87 mph
    • P for 150 km/h / 94 mph
    • Q for 160 km/h / 100 mph
    • R for 170 km/h / 106 mph
    • S for 180 km/h / 112 mph
    • T for 190 km/h / 118 mph
    • U for 200 km/h / 124 mph
    • H for 210 km/h / 130 mph
    • V for 240 km/h / 149 mph
    • Z for over 240 km/h / over 149 mph
    • W for 270 km/h / 168 mph
    • (W) for over 270 km/h / over 168 mph
    • Y for 300 km/h / 186 mph
    • (Y) for over 300 km/h / over 186 mph
  • This is a very easy to understand breakdown of the previously confusing notation on the side of my tires. Thank you for the detailed clarification - exactly what I was looking for. Commented Jan 7, 2016 at 12:37
  • Good job with the edit. I can now vote to close my other question on the same subject :)

It means the surface is 195mm wide, the sidewall height is 65% of the width (195x0.65=127mm) and they fit a 15 inch wheel, 195-65-15. These give all the important dimensions of the tyres and shouldn't be changed. Doing so will give you a bigger or smaller tyre which could confuse your car's computers, causing ESP and ABS faults as well as affecting the accuracy of your speedometer.

91 is a load rating, you can look this up on a chart but 91 equates to a rating of 615 kilos. This is the maximum designed load to be carried by the tyre. V is a speed rating, again you can look this up but V equates to 149MPH. This means the tyre is designed to cope with speed of up to 149MPH.

The load rating and speed rating are less critical if you stick to speed limits and bear in mind the weight of your car and its contents.

  • However bear in mind that fitting tyres with a different speed rating or load rating could invalidate your insurance, unless you declare it.

  • Thanks for that info, I'm only 18 so that is an important consideration for me. I guess I should stick with the 195-65-15 dimensions but wouldn't a tire like 205-60-15 give me more grip always with more surface area in contact with the road? Commented Jan 7, 2016 at 10:18

    I would concentrate on buying good quality tyres, rather than marginally wider ones. Wider tyres of the same type might very slightly increase grip, but fitting the wrong size could have an adverse effect. The manufacturer's engineers designed the suspension to work with a tyre that size, a different size may not work as well and could even reduce grip. A 205-60-15 has a slightly smaller rolling radius than a 195-65-15, which means your speedometer will over-read. Also, if you don't change all your tyres to the new size at once your ABS/ESP/TC systems may go into fault.

    The difference in circumference is marginal: 190.5 vs. 192.9mm makes 2.4mm (0.1") less. Speed will be about 1% lower than displayed, and I can't imagine that this could cause trouble with ESP etc. And yes, I agree: 10mm (0.4") wider tires won't give more grip.

  • I agree it probably won't make a difference in this case as the difference is within the wear limits of either tyre but I'd like to make the principle clear that (at least on modern cars) having odd sizes across axles can cause problems.
