Like i've said previously, T1R's are a good mid/high range tyre. Great in the dry, i drive back from whitby most saturdays at 3am, can see cars coming quite far ahead in the dark so you can treat that road like your own private racetrack. Last week the roads were dry and it wasn't frosty, i thought the toyo's were superb, infact it was one of the best drives ive had, from whitby to cloughton in about 10 minutes. However the journey today, the roads were damp, totally different story. Thing is though,weathers going to get better from now on so come the summer your going to be reaping the rewards.
Steven, the price difference between 50 and 55 is quite considerable, enough to make 50's very tempting.
