Rich Vaughan Posted January 25, 2020 Share Posted January 25, 2020 Hi, I'm just completing the build of a Pre-lit 7SE with 1700 Crossflow. I'm currently looking at which tyres to use. I have over 10 years experience running a bike engined single seater on Avon slicks in sprints and hill climbs, but my choices now in Mod Prod are wider and I could use some input. I did intend to use Pirelli Ultra slicks, but as I'd like to also use the car for the odd track day I am contemplating going for a compromise and use either 1B or 1C tyres. Obviously the 1B and C tyres won't be as fast and effective as the slick but by what margin? Typically what do other competitors use in W3?

AdamR Posted January 26, 2020 Share Posted January 26, 2020 What about Yoko A021R? Unsure of time difference to slicks but they are pretty soft and will work in the rain too! Quote Link to comment Share on other sites More sharing options...

Yes maybe, but this is a foot in the water season, so I just want to get a feel as to where development of the car should go without too much expense Quote Link to comment Share on other sites More sharing options...
John Loudon - Sponsorship Liaison Posted January 27, 2020 Share Posted January 27, 2020 How about a set of slick cut to inters? However, given that we usually have very few wet sprint days versus dry sprint days, I would stick with slicks and just bite the bullet when it rains Quote Link to comment Share on other sites More sharing options...

K17 CAR Posted January 28, 2020 Share Posted January 28, 2020 To be fair the nature of sprinting means even on a wet day you'll be unlucky if it rains all day, it's not fun in the rain on tyres not designed too shift water but once it's drys all the previous efforts on "wet" tyres are lost with one dry run, or if it rains later in the day no one is going to improve on their dry times from earlier whatever their rubber. my choice as tyres are free in your circumstances (just running one set) would be Kuhmo V70's they offer great dry grip and won't throw you off in anything but the worst of standing water. it just so happens I have a set avaible in super soft if your interested as I can't use them in road going?

Thanks I'll give it some thought, what size are your v70's. I'm running 13" x 8" wheels front and rear Quote Quote Link to comment Share on other sites More sharing options...
K17 CAR Posted January 29, 2020 Share Posted January 29, 2020 I have 2 brand new 215/50/13's and 2 235/45/13 that have done 5 sprints, all four are k12 super soft. Quote Link to comment Share on other sites More sharing options...

Rich Vaughan Posted January 29, 2020 Author Share Posted January 29, 2020 Thanks for the info on the tyres. I still need to weigh up the pros and cons - slicks against moulded slicks. TBH at this stage I'm erring in the direction of full slicks and those will probably be Pirelli Ultra softs. Quote Link to comment Share on other sites More sharing options...
K17 CAR Posted January 30, 2020 Share Posted January 30, 2020 That will be the tyre too have. Quote Link to comment Share on other sites More sharing options...
