Hi. Could anybody assist me. I am lkooking for tyres for my Testarossa. Front size is 225/50/16 and rear is 255/50/16. Also car feels extremely unsafe after 210km/ph, as if the nose is starting to float. Is there anyway that this can be corrected by using spacers etc. Lastly I have a intermittent problem. The right bank of engine will cease to fire and then only runs on 6 cyclinders(or feels like it). I can park it and next day it will be fine. I have swopped the coils around, but to no avail. Could it be fuel pump on left side.....? Thanking you kindly in interim rgds

A set of 2 rear and 2 front for $1,700 plus tax, shipping, mounting, balancing, etc. for four tires. The Coker Web site indicates TR tires to be Michelin Pilot tires. That seems odd. I thought they were Michelin metric tires or Goodyear Eagles in 16 inch sizes. (1986 Testarossa) I'm running 16 inch Kuhmo tires for about $400 - $500 in total. They are fresh rubber and modern designs in my old sizes. I have been pleased with them over the past year or so.
I just put BF Goodrich tires on after the Dunlops wore out. I have been very happy with them and very reasonably priced.
(Assuming that you also already checked the dist rotor/cap/button and coil wire and all was OK) Yes, it could -- the relay labeling refers to the mounted positions of the fuel pumps, not which bank they serve -- i.e., the relay labeled "LH side" controls the fuel pump mounted on the LH side of the chassis which serves the RH 1-6 bank. The first thing you should do is unplug the "y" white connector (which requires first unplugging the "x" connector above it), and see if the connections for the fuel pumps are "burned" or not.

Not for 544.00 EACH I'm not!. As much as I hate them I'll stick with my BF Goodrich G-Force for 1/10th the price, and they are speed rated too. What Coker needs to do is make a 265/50-16 to properly fit those rear wheels. The 255's are actually a little too narrow.
Goodyear isn't making the 255/50-16 anymore from what I have found. Do you have another source? Ideally a 265/50-16 is what is needed on the rear.
225's in the front. 255's in the rear. The sidewalls of the 255's curve inward somewhat and would look a lot better with 265's. Actually, it would look and handle better all around with 18" wheels and tires off of a 512TR
Michelin was an option for the 16" wheels. Check with http://www.longstonetyres.co.uk, they carry Michelin's also.
Better than the Coker price of 544.00 each USD. Longstone "only" wants 440.00 each USD for the same tire. In my book the 255/50 is still too narrow for the rear wheel on a TR. Ridiculous..............................
+1 to Spasso's comment too. A 265/50/16 however is virtually non-existent in 16" sizes. However, 265s and modern 275s and 285s are available in the bigger diameters with correspondingly low Aspect Ratio (profile series). I had a Skyline GTR-R33 that ran on 265/35/18 Yoko Advan.... That said, a 285/45/16 tyre should be a good upgrade and with only a 1.5mm increase in total overall diameter, plus a 15mm either side of the rim to prevent kerbing and most importantly, the extra rubber on the road... The AR is lower at 45% compared to 50% of the OE tyre but at 285mm section width, yer total rolling diameter will be the same. < total OD of a 255/50/16 is 661.4mm. Total OD of 285/45/16 is 662.9mm> Good Luck.
Well said. I use the spec chart on Tirerack to figure ultimate width and diameters depending on base wheel diameter versus tire aspect. I thought I had scored big time on an alternative to the 255/50-16 when I found a Khumo Ecsta W710 (229.00), 265/45-16 listed but sadly only comes with a "30" treadwear rating versus the desired 180 to 300 desired for street use. They also have another Khumo Victo Racer (192.00) with a "50" treadwear rating. I bet the Khumos are a blast on the track!
I've made this change and I'm really happy with it. Improved handling, grip and looks. Just don't forget to purchase spacers and new bolts.
In my car the same connector burn a few months ago, left electric ventilator stops, i was repair it but with too many hours of work. regards.
Steve and the boys are right on track with the fuel pump / check connectors at the fuse board. If you need further info go here: http://www.testa-rossa.info/fuse_panel_repairs.htm On the 210 km/ph floating issue, mine also does this. It's not as obvious on the track but on normal roads with a bit of uneveness she moves around like a Latino pole dancer! Really hard to handle. Hard braking into a corner also upsets it, so I put the problem down to soft front shocks. I visited my local Koni specialist and they have suggested a rebuild with +20% stiffness for our crap roads and the way I drive (spirited!)
BTW: I run 512TR wheels with 235/40-18 fronts and 295/35-18 Michelin Pilot Sport II tyres. Some say they are the World's best tyres and I would have to agree with them, yet my car still moves around badly at 220 - 250 km/ph, hence I don't consider tyres or wheel offsets to be the issue, but something more mechanical.
