A 165HR400 radial tyre with the correct taller diameter with superb handling and ride characteristics. These period correct steel belt construction Blockley tyres are the best 165R400 ever made, and you will not believe the improvement in handling that these 165HR400 will result in over what you have previously experienced. This 165R400 tyre size was standard fitment for many Lancia models (Aurelia, Flaminia, Aprilia), Alfa Romeo 1900, Ferrari 250 and the Citroen Traction Avant. The 165R400 tyre size was the first radial tyre available for sale to the public, before radial ply tyres started to become more mainstream about 10 years later.

This Blockley 165 HR 400 is a properly designed full diameter steel belt construction Radial ply tyre, with a good speed rating (H speed rated - 130mph / 210kph) and period correct tread pattern, designed in house, offering improved handling and ride characteristics compared to whatever you have driven on previously. The 165R400 tyre is also a useful radial replacement for the cross ply tyre sizes 130x40 and 140x40. These Blockley 165HR400 tyres are E marked as well as DOT marked for use in the USA. And what appears to be the low list price of this tyre is only because we sell direct to the end user / garages and avoid the mark ups of the Classic tyre wholesalers.

Please note that Pirelli (a brand owned by the Chinese government) claim that their Cinturato "CA67" 165HR400 is the only H speed rated 165R400 tyre, but this is not a correct statement. The Blockley 165R400 tyre is H (130mph) speed rated, but the big difference with the Blockley is that the Blockley 165HR400 has the correct larger diameter that this tyre size should have!

Blockley produced this 165HR400 tyre in order that there could be a good speed rated and infinitely better handling tyre than the Michelin which was the only 165-400 tyre option, because something much more wholesome has been needed for some decades. Knowing the Lancia Aurelia and Flaminia Zagato pushed us to commit to this unusual millimetric 400mm wheel rim size, which required much in the way of specialist tyre making tooling. Since starting this project Pirelli also have produced this size with the same speed rating as us, but the Pirelli diameter is too small! These 165R400 Blockleys will be the best you have ever driven on and come with the usual Blockley radial tyre guarantee, which is to scrub them in for 30 miles or so and if you are not overjoyed in every aspect over the next 1000 miles or so we will offer a full refund. Anyone previously using a 165R400 tyre size is in for a nice surprise!

The 165R400 is also a good tyre size for a Traction Avant Citroen over the cross ply 130/140x40 and 150/160x40 cross ply tyre sizes available now, the Blockley with great handling and very cost effective alternative choice. The 160/40 tyre size was listed with Citroen from 1932 and the 165/400 size was listed with Citroen from 1939, and used on theTraction Avant until production ended in 1957.

Please note that as per original period specification this 165HR400 is a tube type tyre, just as the 165R400 size was in period, so you will need to fit a correct fitting inner tube which we also produce - as shown at the link below.
