Been a while since there's been a tyre thread on here.. seriously though spent ages looking tonight and couldn't find anything quite right so thought I'd gather opinions. Seems I only have two choices to replace the tyres on my car which are now way too old - haven't been driving it because of this, they've gone noticeably too hard and are 10 years + old now.

It's an R plate Chim 450 with PAS and factory fit Estorils. The question is do I sacrifice a bit of tyre width at the back to get into Rainsports? I know I don't need a 245 tyre but it came that way from the factory and I like a fat tyre at the back. Just fast road driving, no track days but occasional drag strip runs. Have adjustable shocks also. Have read conflicting reports on how stiff the two options are, Toyo has a higher load rating so assume this is a slightly stiffer sidewall than the Uniroyals? Not after ultimate grip as I think the car is more entertaining with a bit of slip.

Current setup is:-
205/55 16 88V Toyo TR1
245/45 16 94W Toyo T1-S

Option 1
205/55 15 88V Rainsport 5 £75.80
225/50 16 92Y Rainsport 5 £74.60

Option 2
225/50 15 91V Toyo Proxes TR1 £72.65
245/45 16 94W Toyo Proxes TR1 £94.55

Thanks all for thoughts / feedback

All in my humble opinion.

I have had a variety of tyres on my Chimaera over the years, but not Rainsport 5s (I am currently on Rainsport 3s) and not Toyo TR1s, so I cannot comment on the grip levels of those two tyres.

My Rainsport 3s are awesome in terms of dry grip, and are great even in the wet, so good that I have them on my daily Saab 9-5 as well. They turn the Chimaera into a normal road car, no pussy footing around required.

On sizes, I have had both 215 and 235 on the rear of my car. Honest answer is that I cannot tell the difference. I drive quickly but sensibly on the public road, not close to the limits of grip, and have appropriate track tyres (currently Toyo R888R) for my track days. The overall grip level of the tyres is, in my opinion and after 45,000 miles in 9 years, more important than the extra few millimetres of width at the rear.

My car is also a PAS 450, but turbocharged.

A very similar modern car in weight and balance would be the Mk 2 Mazda MX5.
They run 205 all round.
I’d go for the tyre with the most grip rather than any size differences.
A narrower tyre can work in your favour especially in poor weather conditions.
Most TVR with standard 22/24 pressures stationary the tyres look like there is barely any weight on them so depending on tyre you could get a narrower or softer tyre that squats more so in fact has a wider contact patch.
I run RS3 also and love them to bits but my car is on 17in rims so less tyre wall height than standard.

I have been running your option 2 (T1R's when first set fitted) on my Griff 500 for 11 years and after experimenting with pressures a little been very happy with them in all conditions. I found 22/24 psi too soft but upping to 24/26 is perfect, for me anyway!

I wouldn’t bother with Rainsports.

As I needed new tyres recently, I read plenty of tyre test reviews which compared the usual shortlists (Yokohama’s, Bridgestone, Michelin’s etc, etc).

As such, I went for Goodyear Efficientgrip Performance- the reviews rated them as superior to most others including Rainsports, even in wet grip situations, where you’d expect the Uniroyals to excel.

On what car were those tests complied. Was the car as light as a Tvr for instance.
I don’t think those tests prove much unless tested on this car.
Do you have experience of both sets of tyres on this car or just the ones you have chosen.

I have no interest in pissing contests so I hope your right thumbup

I was thinking of asking a sales assistant to come round to my house with a selection of vacuum cleaners to try on my carpets and hard floors but in the end I gave up on that idea and read some online reviews. Very happy and saved loads of time and hassle.

Please credit me with some understanding.

Obviously if the tests were carried out on a front wheel drive family saloons, they would be meaningless.

However, the comparable tests were carried out on light RWD sports cars.

That’s good then.
What car was it out of interest.

as alluded to earlier, and in my experience RS5's don't provide lateral stability and undermines confidence cornering and high speed stability, really not where you want to be. I went from Toyo TR1's to RS5's to Michelin Pilot Sports on the rear and I'm not looking back, MPS's are expensive but worth it

I have a pair of RS5's free to anyone who wants to pick them up (Raunds), perfect condition with approx 2k Road use only. First to PM me gets them but they are only what they are!

2 off 225/50/R16/92Y, date mark 2520 (so halfway through last year)

OP, I know they aren't on your list but I have just fitted Yokohama Advan Sport V105 on the rear and am highly impressed.

Please note however, that even though I have a car similar to yours, I may be a st driver and probably don't know what the fk I'm on about, so please ignore me at your leisure.
