The original 600 tires were 9.00x15 Fulda's (named for the town in Germany in which they were produced).

Today, that ancient designation translates into one of two tire sizes: 235 75 HR15 or 225 75 HR15. Both of these tires sizes will work fine for a 600, but you MUST make sure of one important spec: Extended Load capability. Michelin tires can be ordered with this spec, as can Dunlop and Coopers. This is important because of the weight of a 600 SWB or LWB, between 5400 and 5800 lbs. A regular tire just won't suffice.

The speedometer may be off a bit depending on which size tire you purchase.

Gerrett, are those tires available with a white stripe, or as white sidewalls?

Hi Joe, how is Life ?? I hope your doing well

I changed last year my fronttires:
You can choose:
900x15 or L78x15 or 235x15 or 235/75x15 or 255/70x15

I could in Europe not get the originals Fulda-tires so I choose:
General Ameri G4S 235/75/15 Allweather-tires with a small white ring that is allmost the same as the original tire.

Old thread, new message.

I continue to be dissappointed by how hard it is to find a quality tire in the right size. I spent years trying to find an acceptable tire for the 112 chassis cars, and still had to accept the compromise of going to a 185/80-13. I was sure that finding a decent 15" tire for a 600 would be easy. Wrong.

I am not one of those snobs that believes that much money must be spent before anything of quality can be had, I prefer to think of myself as an experienced, technical person that believes that much money must be spent before anything of quality can be had (snob is such an ugly word). I just simply can't imagine that the highest priced tire that tirerack.com has in a 235/75-15 is all that good at $68.00 US.

Without starting a debate about cost & value about Michelins, let me just say I like them. Every vehicle I have put them on was improved. In my mind they are well worth the money.

Unless I missed them, the Michelin site doesn't show a tire in the correct size for the 600, but I saw the comment above about being able to order Michelins with the heavier load rating. What tire is this?

I agree that a standard conversion of a 9x15 tire would be about equivalent to a 235 width, but looking at the various tire tables indicates that modern 235s are designed for a much narrower rim than the 600's. This implies that a tire could much wider than 235.

Since you fine folks have been doing 600s for years, and I am only starting, I am asking if someone could shortcut all this for me and tell me what they are doing and why (and where you got them).

Thanks!

Whoops!

I thought, just for fun, I would have a look at the wheels on the car. Unlike the book I have that apparently has a typo in it, the actual wheels are 6.5x15 making a 225 or 235 quite appropriate for the 600. So please ignore my prior comment about possibly going to a wider tire.

Chris,
I've had #178 for 20 years. When I bought it, it had Bridgestone 1 inch strip whitewalls. I could never get them to balance. They flat spotted when the car stood. I tried every type of balancing to no avail. I even had the wheels balanced. The guys at the wheel shop all got together to look at the wheels because they said they had not seen wheels of that quality in years. They said there was nothing wrong with the wheels.

So, even though the Bridgestones had tons of tread, I threw them away and bought Michelin 235/75 R 15 1" thin whitewalls which totally solved the problem. They were hard to get but I eventually got them from a tyre dealer who had a number of Rolls Royce customers as they used the same tyre. When they started to do the same thing, I replaced them with the current set which are Kumho (Korean I believe) P235/75 R 15 105T M+S 1" thin whitewalls which were a much lower price and more readilly available at the time than the Michelins

The Kumho tyres have been very satisfactory. I would add a couple of other comments. For the average 600, the tyres become unserviceable not because of tread wear, but because of hardening with age, making them dangerous for high speed work. Secondly, when I bought the car, it still had the original 1965 (Dunlop crossply as I recall) nylon belted spare tyre in the boot (trunk)!! It had never been on the car and still had those little rubber bristles on the face of the tread that new tyres have and was spotless, again with a 1" narrow whitewall. I replaced it with a new tyre but kept it as a keepsake for a few years but have since thrown it out.

NO doubt there is a car wrecker in Europe who will be dissapointed to hear that you chucked out a unused Dunlop spare....Right Marc?

Hello Art,

Do you recall what the model of the Michelins were?

Thanks!

Chris,
I couldn't when I typed the reply, but today I have the time to pull the invoice from 23 June 1989 and they were 235/75 X 15 XA4's and they were A$249 each way back then. Of interest, and never noticed before, is an ad for KUMHO tyres on the invoice. Strange coincidence!

Art:

My first set were the XA4's, too, on Karl's rec. I didn't like the look of them, so I had a 'custom' set made to the original '71 whitewall spec - which placed the whitewall much closer to the wheel than current tires.

However, I MUCH prefer the 'old school' wide whitewalls, like the (*sniff sniff*) defunct Firestone 721, with the 2" whitewall. Those looked SOOOO good on my Cadillac limo, which shared the tire size with the 600. I don't think you can get those anywhere without getting them made, which I probably will do at some point.

RE: Kumhos... I got my first set on a BMW Z3 about 6 years ago (the OE tire was a Michelin Pilot). WHAT A DIFFERENCE! I have always found Michelins to be HARD tires, and not particularly sticky for my tastes. The Kumhos were a HUGE improvement, for less than 1/2 the cost of the Pilots. I put a set on my Impala SS, but in that case, the OE BFGoodrich Comp T/A's were superior. However, the only Kumhos in the size I needed (25560R17, I think) were SUV tires. Probably a tactical error on my part, there! BTW, when the Impala came out, it used a tire size EXCLUSIVE to that car. Which meant that the tire dealer required your VIN before he would order the Comp T/A's, since they were in short supply (17" tires were kind of a novelty in '95).

Anyway, if Kumho makes an extended load touring tire in a 225/235 15" size, I'd certainly try it!

The vintage Michelin tires are XVS, size 237/70 HR 15. One of my 600 has this tires and they work well. But the size is not 100% correct (235/80 was the original...).

I had a set of Kumhos on my Cadillac Eldorado (weighs over 5200lbs) and they were terrific. They are the same size and required rating as a 600. Would have gone with Michelins (it's a habit), but I was in the middle of nowhere in New Mexico and one of the front tires delaminated. The tires on the car were practically new mileage-wise, but they were years old and hadn't been used much. I was upset at first to not be able to get Michelins, but it worked out quite well. Those Kumhos laid a pretty mean scratch.

Don't I recall that Karl said you could also put 255/70s on a 600? I swear that's the case. I forget who makes the tire, but I'm almost sure he said that.

DaimlerChrysler recommends as an alternative size for the 600 SWB only the use of 235/70 R 15 tires, which are available from various sources. The tire pressure is altered to 2,4 bar (front) / 2,6 bar (rear) and 2,6 bar (front) / 2,8 bar (rear).

Aggie, what does the 235/70 x 15 tire size do to the accuracy of the speedometer? I have the 235s on my 600, but in the 75 series radial, and this causes the speedometer to read higher than actual speed. I believe the 70 series radial would incrase the speedometer error even more.
