Looking at some Ziex ZE-512 Tires for my 1990 GXL.
I'm hoping to go 225/60/R15 all the way around.

Anyone else tried these tires before or have any feedback? I've read some reviews on them and they got 4.3 out of 5. Only thing people really commented on was the weak sidewalls.
I phoned around and can get them installed for $510 CAN with tax. Good deal?

If someone thinks i can get a better tire for the same price please speak... All im really looking for is 225/60/R15, with good tread life, and decent handeling. I don't do autocross or anything but still would like it to handle good. I would also like something with a semi agressive tread.

Thanks

 

No experience with the Ziex, but I've seen them mentioned in a number of threads, and they get good comments...for the price.
I know the FC Series 4 came with 205/60-15's as stock tires. If your series 5 is the same, 225/60-15 will give you about 3 inches more rolling circumference (i.e. a taller tire). Acceleration will be theoretically slower as you have effectively made the gearing 'taller' with the larger tires. The series 4 GX and GXL came with 24.2 and 24.7 diameter tires respectively, with the same transmission and drive train. The 225's will give you 25.6 in diameter tires. 225/55-15's (if they make that size) should give you the same (24.7 in) diameter as your current tires.

 

these tires are decent for the price. don't expect much grip out of them compared to other tires. i tried these out at buttonwillow east loop and they held up for a lap well, but started to get a bit loose after they started gettin hot. you shouldnt' have any problems with these tires since you probably don't beat them up as i did.

 

What if i were to go with some 16" convertible BBS style rims im thinking of picking up?

I imagine it would either be 225/45/R16 OR 225/50/R16...

Which would keep the same diameter as my current tires?

 

87cncnu, How do "wider" tires make a tire taller????

205/60/R15 Should be the same diameter as 225/60/R15, only wider..... ??

Im confused..

 

Can someone please explain this to me???

What if i were to go 215/60/R15... Would this keep the same diameter as stock?

 

Don't know if this info is worth anything but...


I took a "Dukes of Hazard" jump off an on-ramp in my old Civic when I hit a patch of gravel and spun out. YES fwd's CAN spin out. I flew backwards almost 10 feet out and 10 feet down into the slow lane and landed on all 4 tires at once. It was a miracle. That means my tires took ALL the force of that landing. I had 18'' 35 series Falkens on there.


I have no idea how they didn't pop and they must of did something right because not one of my rims were bent either.


Falkens go on ALL my rims now. Just out of good luck.

The '205' or '225' number is the width of the tires in mm.
The '60' means that the sidewall is 60% as high as the tire width i.e.60% of 205=or 123mm. If you now go to a 225mm wide tread the sidewall will be 135mm tall (225 X 60%), or 12mm taller below the wheel, and 12mm taller above the wheel, so the tire is 24mm taller.

The way to get around this little problem is to buy a lower 'aspect ratio' tire like a '55' series rather than the '60'. Turns out that 225 X55% is about 123, just about exactly the same as the 205/60-15's you started with.

The 215/60-15 will give you a diameter of 25.2", or 1/2" taller than you 205's and a full inch taller than the GX tires. Whenever you increase the tire width, you have to decrease the aspect ratio to maintain (approximately) the same diameter, on the same size wheel.

So.... you probably want to try and find a 225/55-15 if you want to stay with your 15" wheels (giving a 24.7" diameter, same as your 205's), or go to a 215/50-16 (24.5" Dia) or a 225/50-16 (24.9" Dia. or .2" taller than you have) if you want to buy larger wheels.

Have no idea whats available in these sizes, but thats the way the ##'s work out.

Cheers

 

Play around with the tire size calculator at this site

http://www.miata.net/garage/tirecalc.html

and you should get an idea how it all works. Remember that the GX and GXL had diameters of 24.2" and 24.7" with the same transmission/rear end combination, so anything in between should be OK. You could probably go a tenth or two either side and still be OK, but I wouldn't go much further. Probably find more selection and variety of sizes with a 16" wheel than with the15".
