B7 tyre question

Post by Batfinnk » Tue Oct 16, 2012 6:29 pm

Have found a set of brand new Toyo Proxis T1 tyres pretty cheap. Has anyone had these tyres fitted before and what are their thoughts on them please?

I have had a set on an old VW Jetta ( albeit in 16" size ) I had, very sticky in the dry but not so good on wet greasy roads. ( I managed to spin on a roundabout I have negotiated 100's of times in the wet in various car/tyre combo's ) the kids thought it was cool but the volvo driver behind me didn't :shock:

Kind of answers my question. Thank you. Did read some reviews and quite a few said the same as that. Not sure what to get tyre wise. I only do about 4k a year. They won't need replacing till next year and the wheels aren't pristine but have an identical set that I had on my A6 which I took off before I sold it which have a total of 2 tiny marks on the rim. My plan is to see out the yukky winter weather on these then get the marks done on the good set and fit them with new tyres but just don't know what ones to fit.

I'm running Vredestein Ultrac Sessanta currently and I haven't been that impressed.

They squeal and they let go way too early in any conditions.

Maybe I'm expecting too much from the heavy S4 but I ran Goodyear Eagle F1s on my old Impreza and they simply would not lose grip, even in torrential rain!

I've got 4-5 mm left on these so I'll be testing the F1s in the not too distant future.

Just found a place online who do retread tyres. They do a full set of 4 based on michelin pilot sport delivered for £173. Bearing in mind I only do about 4000 miles a year and it doesn't really get driven hard too much what do we think about a set of these for it?

I'd take Toyos over retreads any day. I don't really know anything about retreads but they don't sound good to me, I'd avoid at all costs unless somebody could convince me otherwise. If you're not doing many miles or driving hard the Toyos will be fine. I have them on my Navara and they really grip. Are they not as good in the wet? Hard for me to tell as an empty navara is tail happy in the wet anyway. Doubt it will be a problem for a Quattro.

This should help explain them mate :)

What it means:

Big manufacturers (in particular Michelin and Continental) design their tyres so that the casing (basic infrastructure) can be reused. Worn tyres are collected and taken for a safety check. If they meet the quality requirements (are not damaged, not split, not too old, no puncture and worn evenly across) then they are supplied to third party companies such as Profil.

In the case of Profil, tyres are first quality checked and then the old rubber is buffed off the original casing (basic infrastructure), so new rubber can be fitted. From here onwards retread tyres are made exactly the same as brand new tyres.



In the next step they put a new premium quality rubber on the old casing (beads to beads) and put the tyre straight into a hot oven of 120 degrees for about half an hour.

The result is the retread tyres are capable of high speed ratings and good load index, comfortable thanks to the original casing, good grip from premium rubber, lower road noise due to the pattern engineered by e.g., Michelin. The E20 is the safety standard tyres have to meet to be used in European countries.



And last but not least THE ECO FRIENDLY TYRE.

Just to give you some information about how safe retreaded tyres are: single airplane tyres are retreaded up to 8 times, and single truck tyres are retreaded up to 4 times



Are remoulds same as Retread?

No

Although remoulds and retread tyres both contain old casing and new rubber, remoulds were made using old school glue and cold rubber on top of the casing. Retread tyres are made using the same procedure as new tyres, specifically, beads to beads moulded and hot oven. Therefore retread tyres are better quality than remoulds tyres: better speed ratings and load index, more comfortable, better grip and lower road noise.

Fair point about the flip side of them but that article is from the other side of the water either the states or Australia. I may be wrong but surely our specs or rulings must be more stringent or stricter over here in blighty?

Tbh I've bought a set of four for the missus pug 306 diesel. She only does about 2000 miles a year and all local work and mine won't be needed for a few months yet so can sort of use hers as a bit of trial run on how they perform. If they are shot after 6 months for £115 it's not much of a grumble.

I'd imagine an S4 will be putting the tyres under a lot more stress than a pug diesel though.

ever heard of 'killer colways' ? their bad reputation was deserved as the retread often parted from the casing (its glued on) , you may as well fit nang kang kippa bangs to your car for £60 a corner. I never budget with tyres and would never fit retreads to any car capable of 155mph ?!?!?!?!

I used to run Toyo Proxes T1-R's on my old Mk4 R32 (235/35/19) on my BBS CH's and couldnt stand them.. they felt too splashy. alot of movement in the rubber, and it made me lose confidence in my cornering.

that said, i have now been running the Proxes T1 Sports on my b7 s4 for over a year, and they are an excellent all-rounder and reasonably priced.. if they are good enough for Audi to put on the RS3 and RS5 from the factory, they're good enough for me!
