Stock 71 240z needs tires, pics please


Recommended Posts

put new Kumho Solus KR21 - P185 70R14's on last year, only seen about 200 miles so far since we have a little issue called snow up here! They hold the corners great and look great on the car.

I have them installed on my donor car right now, but no pictures, if you like I can shoot one tomorrow.

[ATTACH]34772[/ATTACH]I will sell you these will and tires which are 205 60 14.Make me an offer

Don't want the wheels... shipping would be silly to pay for for used tires that are not so expensive new (and with a rad hazard warr)

Currently running 195/60/15's... 24.2" or there about in height. I was actually thinking of parting with my 15" panasports...

Looking for more performance oriented rubber.

205/60/15's rub on my front bodywork, just BARELY, and I refuse to bend it or cut it.

The list of quality tires is just about 0 for 15" rims in the 195-205 section width. However, if you go to 16" the world opens up, and it rains valve stems and fords and chevies get along... all is right with the universe.

However, I have also been thinking of going to a 14" rim, as I can get more race tires in that size in a 195 to 205 section width (thank you miata owners of the world)

Something to think about if your car is a good weather only garage queen like mine.

Have you fitted 205-50 for rubbing? They're a little more than 1.5" shorter than the 60s...

On my first Z we had the same fitment problem the problem it is not height, but width in the front. The 205 would fit nice in the back however. If you haven't added torque to the power band stick with a narrower tire you get better gas mileage and quicker turning response.

I totally agree with that statement forester. I noticed going from a 205 to a 195 that my car felt livelier and crisper.

On a side note, if you are talking about rubbing on the front end of a Z, when I had my MSA front air dam, I had none at all with my 205/60/15's. It is only when I switched to my OEM front with the spook I had some rubbing. I thought about ways to fix it. I loosened all the bolts and moved parts around, but no joy. I still had the slightest rub on the passenger side.

Since your tire moves on an arc rather than a pivoting around a point, you can solve the tire rubbing in two different ways. You can either reduce the aspect ratio, like going from a 205/60 to a 205/55, OR you can reduce the section width, like going from a 205/60 to a 195/60. BOTH reduce the tires overall diameter by a different amount. One shrinks the sidewall while keeping the width the same, the other reduces both a little bit. I wanted to keep my overall diameter close to what I had, and the 195/60's were a very nice fit.

My clearance issue was the sub-frame (or the equivalent)when fully turned on the front side. Just barely.

Ya I've laughed so many times inside my self with people telling me they want their car to handle better so they put bigger or wider tires on or they think it might help with acceleration. Never thinking about wieght, tire drag and torsional deflection of the tire, and several other factors. The other is when people over look brakes as a performance upgrade tires and breaks are what win races on a track. Every change effects the car and makes more change a car is a package every part(or lack of) counts to how it performs.

Sumitomo HTRH4's, 195/70 - 14's on American Racing Libre's - with Euro Spec. springs and KYB's. Purchased from Sears on 9/08/2005 for ~ $50.00 apiece.

I'm running the same wheels and like the way the Michelin Energy MXV4's ride. Great traction. Little road noise, and they sit a little wider, giving the car a solid look.

Ok... so I bought a set of relatively cheap Cooper Response Touring tires at Sears in 195/70R14. They have a plain retro look to them.

My question related to the slotted wheels: I need lug nuts and I need center caps....

I have a few lugs that fit but I'm having trouble sourcing replacements. Is there an online source that stocks a multitude of lugs so I can find what I need?

Center caps... I just want something simple. Retro cool would be great but I don't want to spend a ton of time or money on these...

any help would be appreciated...

My '70 is currently shod w/Yoko 195/60-14 on 39 year-old 6" Fentons. Tire diameter is 22.5 inches.

Since installing the R200 w/3.90 gearing, I notice that at indicated legal speeds, I'm getting passed like I'm chained to a post. My shop said the speedo gear I had w/the old 3.36 should be "real close." I'm beginning to think otherwise, but need an excuse to upgrade to 15 or 16" wheels, hence my question...

What is the OEM tire diameter for this car?

Of course you can change the driven gear on your speedo cable at the tranny end. Figure out how much you ar off now %wise and check the other gears available. Count the teeth etc....... you get the picture.

ALMOST ready to run down the road with it for the first time!

Did the hoses, master/slave clutch cyls, fuel lines, vac lines, rear shoes...

Just today I finished up with refreshing the front suspension: ball joints, rotors, tie rods, sway bar bushings... I just added new brake pads and have found that indeed the calipers need to be replaced... I think I'm going to just do the Toyota caliper upgrade while I'm at it...

New tires too...

Here how it sits as of this afternoon:

Mark, I bought some nice lug nuts at Pep Boys for 2 of my 240Zs with the slotted mags. They are made by Rally -model #90145 and are 12 mm x 1.25 and come in sets of four. The center caps and the 'Z' stickers that go on them can be purchased from MSA.

So what exactly are these wheels called or referred as? I have them on my car and am curious. Plus, what's with all the white spots on the wheels? I see that there are other members with the same issue. Is that something common with these wheels?

Oxidation I presume...? Same as happens on an old, unpainted aluminum screen door.

Anyone know what size tires these would be with modern sizes. They say 185 sr 14. Im thinking 185/75R/14 but not sure. I wouldnt mind getting a little wider tire on my stock steel wheels but I want to keep all the height. So reading Arnes post Im thinking 195/70R/14. Will that be the same height but just a little wider? I dont care as much about the width as I do about how tall they are. These fill the wheel wells perfectly. Thanks.

Hi Brian.

The original Bridgestone spare that I have is a 175 HR 14. 195/70 14 is very close to the same height. I'm attaching several photos. One compares the height of the two tires (with the 175 HR 14 being just slightly taller). The other two just show the tire sizes. My 195/70 14 is a Sumitomo HTR H4 mounted on a 14 x 6 Libre, the Bridgestone is mounted on a stock steel wheel. For what it's worth, if you do search on Tire Rack for a 1971 Datsun 240Z specifies 195/70 14 as original equipment size.

http://www.tirerack.com/tires/SelectTireSize.jsp?autoMake=Datsun&autoModel=240Z&autoYear=1971&autoModClar=

You will find that Arne's recommendations are typically very accurate.

Thanks Gary. Just ordered 195/70r/14's. My car is lowered a bit and I love how the wheels tuck under the fenders. Hopefully will have this thing back on road in a month or so(That pic is of my 1st z...which we wont talk about).
