Which tyres work well with a 4.3?
Discussion
I have almost run in my new Power 4.3 in the Tam so am now thinking about what tyres would work best with the extra hp and torque. Currently I am running Toyo Proxes T1-Rs and to be honest they have been fine with the 3.6 but maybe I should try something different. People seem to like 888's but I bet they are not so good in the wet. Has anyone tried the Proxes 4 or R1R's? Both look better than T1-R's but perhaps offer better wet abilities than the 888's. I am not looking to track right now so for fast road and I have Nitrons. Andy advise appreciated, thanks.
I don't believe Toyo makes the T1-Rs any more - I fitted their new T1-Sport (to a 3.6) 3000 miles ago. The V-pattern of thr T1-R is no more.
Of 888, R1R and T1-Sport, the best tyre depends what you use it for.
I should note that I haven't done side-by-side comparisons of the tyres in different conditions, this is based on experience of different cars with those tyres and discussions with owners.

- Dry weather, keen driving, in warmer conditions, the 888 should be best. Ok in damp conditions, not good for standing water.
- For the above, plus the ability to disperse more water, the R1R should be best. A little less absolute grip than 888 on a dry track.
- If you want to use the car in colder conditions or winter, the 888 / R1R compound will be much less suitable and the T1-Sport should give the most grip.

They still do the T1-R but no longer do the old T1-S and that's not the same as the T1-Sport just to confuse matters.

Following on from that buy a second set of wheels and get some winter tyres fitted if you use the Tam all year round, they work much better in cold conditions wether its wet or dry.Of 888, R1R and T1-Sport, the best tyre depends what you use it for.

Can only comment on the Vredestein Ultrac Sessentas I recently had fitted to the Sag, they are an equal to the Goodyear Eagle Assymetrics in the dry and have better grip in the wet.
I found T1Rs couldn't cope with my 4.3 under acceleration in any gear below fourth. If you only use the car on the road I'd go for R1Rs. Same compound as 888s but with more grooves for the wet.
I run 888s as I track mine regularly and have found them unbelievably good at dealing with the power the 4.3 puts down. I have also found them fine in the wet even on track; you just have to be aware of the limited ability to cope with aqua planing but that doesn't mean there useless in the wet. If the tyres up to temperature the grip is still excellent. It's personal choice.
Another thing to bear in mind with R1Rs or 888s though is the sidewall is very stiff which means they tramline, the ride is a bit harsher and there is road noise on a motorway cruise. Don't let these things put you off though as the grip is fantastic, but that does mean they are compromised elsewhere.
As mentioned I should really get a second set of wheels so I can run different tyres in the winter but it's not an everyday car for me so it's not really a problem.

888's have done quite a few thousand, performance as above, noticeable tramlining on road crests, something to watch for on A and B roads.
Had a few motorway runs with standing water (Scotland - bound to be!!) and was very cautious at first, but now very confident in their ability to deal with pretty much everything that comes along.
Drove straight through last winter, although it was not as bad as the previous two, some good frosty, icy days, and a few with snow: taken steadily, no problems at all. Prefer them to Eagles.
They do shed a terrific amount of water, almost a cone like effect off the sides of the car.
Road noise is much the same as the F1's, not really noticeable, exhaust note sees to that!

Thanks for the advice....I think R1R's are probably the way to go with almost the as grip as the 888's and better wet abilities, given the current summer weather, not a bad idea.
888's when up to temperature may grip too much! ......and break the gearbox on change up, know to happen

Just spotted a problem, they don't do them in the sizes I need for the Tamora. I have 225/35/18 front and 235/40/18 rear and they don't make R1R's in those sizes!
R1Rs are available in 225/40/18 for the front which others have found to rub slightly on full lock, they are approx 20mm taller, raising the front of the car by approx 10mm, on my early Tam they also rubbed at the top under the arch.With the 4.3 you may find fitting a wider back tyre helps in putting the power down, they are available in 255/35/18. This rubbed on the top underside of the drivers wheel arch, on measuring the body/ chassis tolerance I have since found the body on my car has been fitted with the body offset by approx 5mm to the passenger side which is the main cause of the rubbing, on looking at several other Tams it appears I am far from alone.
R1Rs are a very square shouldered tyre which can exacerbate any minimal clearance issues !
If you want a chat PM me your mobile and I will try to help you through the different combinations
Big fan of the R1R’s – Running 265 rears, I had to make some small modifications to the inner arch to stop them rubbing. Increasing the camber also helps, I have been told these types of track tyres like a bit more neg camber.
The result is good wet grip and insane dry grip once warm; no more wheel spin in 3rd gear

Good to know, what are you running on the front?The result is good wet grip and insane dry grip once warm; no more wheel spin in 3rd gear
For all the Toyos you will need to change the profile for the front to 225/40/18 from 225/35/18 which is an unusual size. By changing to 225/40/18 you increase your tyre options a lot but have to be aware of rubbing on full lock. I have Nitrons with adjustable ride height so the clearance is fine.
I use 225/40/18 front and 245/40/18 rear. I was advised not to change the profile of the rears from 40 to 35 by Str8six. Apparently it makes the rear very skittish so i didn't change it but i did want to go to 255, the more the better especially on track!

Thanks for the above, I would go for the same as you front and rear plus I also have nitrons so the hight can be adjusted. Do you get any rubbing with the 245 rear?

No its fine although the inside edge of the tyre is very close to the chassis although this is due to toe in/out settings on the car. If i had gone for 255 they would not have fitted!
I'm glad i played it safe and went one size bigger than standard with the same profile and had no issues. Bear in mind also that the official width for the Toyos is actually half a centimetre less than it actually is! So a 245 tyre is actually 250 wide and so on, and being very squared shouldered means you have to be careful to not go too big with them.

Thanks, I am not too bothered about a bit of rubbing on full lock on the fronts and good to know that rears are fine. I will get the fronts done soon as they need doing. The rears I will keep on for a bit as they have loads of tread currently but I think the 4.3 will reduce that in no time.
