I bought JH 18397 a couple of days ago. It's a lot of fun - and will be even more so when I get a few things sorted out. This board has already been very helpful. I'm certain to have a bunch more questions soon.

What is the correct tire size? I think I read somewhere that 185/70/13's were stock. My car has 195/60/13's on it and the spare is a 215/60/13. The 185/70/13's are readily available and reasonably priced. I have not searched hard yet - but the latter 2 don't seem to be available - via internet search.

205/60-13's are a very popular upgrade to the stock 185/70's. I've never heard of  195/60-13's being fitted to a JH; they would be much smaller in diameter than the stock tires or the 215/60's, and would really throw off  the speedometer and raise RPM's for a given true road speed. I have 205/60-13 BF Goodrich Radial T/A's on my car, and I like them. I've also seen good things written here about Sumimoto tires of that size. Both brands size 205/60-13 are readily available at tire stores in my area, and probably in yours too.

Have fun with your new old car!


(Sorry, I've corrected the tire size above from 215 to 205.)

The stock tire size is 185-70HR13.  This is entirely adequate for the street, but a 205 or 215 tire gives you a significantly larger tire contact patch, which adds considerably to the car's cornering potential.  The tradeoff is usually a slightly smaller tire diameter.

Whatever tires you select, I suggest that that they have 'A' or 'AA' DOT ratings for traction, heat, and wear.  Such tires shouldn't cost any more than the rest, and are usually  far better made, so you'll have fewer balance problems and a smoother and quieter ride at all speeds.  This can be very significant in a car as light as the JH.

I prefer H-rated tires myself as their sidewalls are generally more firm than those of tires with a lower speed rating.  This gives a slightly stiffer suspension, and a JH with stock springs will benefit from this.  Also, if a tire should suddenly lose its air, the stiffer sidewall may allow the car to remain under control for a few extra seconds -- a potential lifesaver.

I recently installed a set of Sumitomo 205-60HR13's on my car, and am delighted with them.  The price was quite reasonable, traction and cornering are very good, steering is precise at all speeds, and they don't respond badly to roadway imperfections.  One does have to pay attention on wet pavement, however.  While this is rarely a problem where I live, one might want a different tire in the soggy parts of the country.

I am considering ordering some Kumho185/80/13's for the 10 hour freeway cruise to the West Coast Nationals. I figure they are about 7% larger in the diameter than the 205/60's that I run now. That reduces my 70 mph cruising rpm from 4000 to about 3720. I have six extra wheels so converting back for better handling is not a problem. At $155 plus mounting it's the cheapest way to get overdrive!

The 60 series tires leave a huge gap between the tire and the wing and look wrong on the car if you ask me. When I win the lotto some large wheels and suitable tires would be nice.

See you on the road,

Kurt Housh

Joel, I can't agree more. I did not get the sumitomo's, but the size has changed the drive incredibly.

I'm shocked to hear that larger 13" tires are readily available. I could not find them in Dallas Tx. anywhere. I couldn't even find the 205-60's on  tire rack. I found the yokes for 40. each but they are a year old and have been discontinued. Can I ask you where you got them and the $.

Tire Rack:

http://www.tirerack.com/tires/tires.jsp?tireMake=Sumitomo&tireModel=HTR+200&vehicleSearch=false&partnum=06HR3HTR200&fromCompare1=yes&place=0

if the link doesn't work, search by size. they also have some racing tires but they were around 150 bucks a pop.

the sumitomos were 42 bucks each plus 37 total for shipping. and the local tire shop mounted and balanced them for 10 bucks each. so - total 240 all the way around. not bad.

ok - next - adjust the parking brake, check the front brakes to see why it pulls to the left on braking, think about changing the timing belt, think longer about adjusting the carbs.. . ..&ct. . .&ct.. . get bushings and swaybars for the suspension. . .find a block and rebuild a motor. . .&ct. . .

just a short list

I think that's a great price. I did look at all those tires. I emailed them to make sure they weren't shaved. Nevered replyed. I was thrown off by the 'competition'.

This JH is going to be for my son for his starter. We will also be try to fix parking brake, replace timing belt, swaybars, all bushings in front. We are now in the middle of trying to recover from trying to install pertronix.

Keep in touch on those projects. Not even fooling with the carbs!! BTW after the yokes I punched it around a corner and heard a little rub.

Joel,

Just wanted to thank you for the Link to TireRack. Bought 4-HTR 60 x13 Sumitomos from them for U$S 210.00 Delivered to Okla. City.

You saved me about U$S 150.00 from the quote I received from local shop. Delivery was 4 days.

Just waiting for my wheels to get back from Powder Coating ($ 35.00ea)

Thanks

Awesome. It's good to give something back after all the info I've gotten from this board in the last few weeks.

Powerder coated for $35 each? Did that include the clean up too? Please post some photos of how they come out. Mine are pretty ugly right now.

Just an aside: I just got back from Japan. Apparently 13" wheels are readily available there - in many sport variations. They have a bunch of small cars that we don't have here and people like to trick them out. I may have a buddy get me a list of tires. It's not too expensive to have things shipped.

Joel, I noticed you put the HTR 200s 205/60R13 on your Jensen. I've been looking at them to replace the current 185s but was worried about fender clearance in the rear. The 185s seem to have about 1/2" which is fairly close with 205s. Any issues with the tires and clearance? Thanks.

Never a bit of trouble.  I've heard these tires are a little squirrely in the wet - but I live in San Diego and don't drive in the wet....:-)

Thanks for the update. I'm not sure my rims are standard but they came with the car. I'll try and check the offset etc.

Is there any gap between the fender lip and the rear tire on your car? On mine it is close enough that you can see that there may be an issue with wider tires rubbing if the car hit a major bump. This leads me to believe that the rim offset may not match the standard Jensen rim. BTW, front seems to have lots of room.

It is very close though - tough to call without buying the tires and trying them on for size. On the other hand the 205s probably look better and I just need to watch the bumps.

Update: The HTR 200 tires are on and look pretty good.

New J-H owner and new forum member. When I opened this topic the first time, I believed I understood how to read a tire size. Now I'm convinced that I don't have a clue. 30-something years of ignorant bliss.

Have the "standard" size tires and currently happy with them...now if I only had a 5th gear...

Have you tried to purchase the 205/60/13 Sumitomos recently. I'm having trouble finding them at a reasonable price.
